What CPAs and Estate Attorneys Need to Know About Sports Memorabilia Appraisals

A USPAP-compliant appraisal is what professional estate planners, attorneys, CPAs, and other professionals should recommend to their clients. Going to a local card show or baseball card shop is not the best idea.

USPAP-compliant appraisers follow professional standards and have the training and expertise needed to prepare formal appraisals. To help your client qualify for a tax deduction or have a greater chance of your case winning in court, make sure your appraiser is USPAP-compliant and understands how to fill out IRS Form 8283.

Wondering what your collection is worth?

Get an independent appraisal of your sports cards and memorabilia from Michael Osacky.

Here are a few examples of when to hire a USPAP-compliant sports appraiser:

  1. Charitable donations: Your client is donating his seven-figure collection to the Baseball Hall of Fame. He will need a formal appraisal report and to have the appraiser complete IRS Form 8283 so he can qualify for the income tax deduction.
  2. Estate planning: Your wealthy client owns a large sports card/autograph collection. He wants to make sure it’s properly appraised and documented for his estate.
  3. Divorce proceedings: Your client is getting divorced. Did the owner of the collection collect during the marriage? If so, the collection needs to be properly appraised so both sides know the value and how to properly split the assets.

In this guide, we’ll cover why sports memorabilia requires specialized appraisal expertise, the professional standards that matter, and what to look for when hiring an appraiser for your clients.

Why Sports Memorabilia Is a Unique Asset Class

Sports cards and memorabilia can be harder to value than stocks, real estate, or other personal property. Here are a few reasons why.

No Central Exchange or Published Price

It can be very difficult to find and understand pricing in sports cards and collectibles. Two cards in the same grade from the same grading company may sell for very different prices at auction.

There are a few websites that provide a general range of values, but there are flaws to these sites. Finding a qualified sports appraiser who understands the market and provides an independent valuation is essential.

Authentication and Condition Drive Value

Many autographs are fake. Many raw cards are trimmed. Numerous jerseys are made in China and sold as game-issued or team-issued memorabilia. Doing your own research using AI only goes so far. Hiring a USPAP-compliant sports appraiser is worth its weight in gold.

Condition drives value. Everybody thinks their cards are mint. An ISA-accredited appraiser has a professional responsibility to provide an honest, objective valuation.

Thin, Volatile Markets

The sports collectibles market is not a mature market like the stock market. Trying to acquire a grail item or selling a grail might not be easy. You may have to give up some margin depending on where we are in the market cycle.

Mixed Collections: Trading Cards, Autographs, Game-Worn Items, and Championship Rings

A collection may include trading cards, autographs, game-worn jerseys, championship rings, and other memorabilia. Each category needs its own research and comparable sales to determine an accurate value.

Provenance and Sports History as Value Drivers

Provenance brings record sales at auction. However, not all provenance is real. People make up stories so their items sell for a higher value.

But if your dad played baseball for the New York Yankees and you have photographic proof pertaining to the item in question, collectors will open up their checkbooks.

Why Fine Art and General Personal Property Appraisers Often Fall Short

Your client is donating his multimillion-dollar trading card collection to a museum. You’ve hired a USPAP-compliant appraiser who signs off on IRS Form 8283. Your CPA finishes the paperwork and completes the tax return. Everything seems to be going well.

Months later, you get a letter in the mail from the IRS questioning the appraisal.

This situation happens more than you think. The CPA, lawyer, or estate planner hired a generalist appraiser or a specialist in a category other than sports. This person didn’t have the necessary expertise in sports collectibles, used the wrong comparable sales, or didn’t fully understand what they were being asked to appraise.

An appraiser may be highly qualified in fine art or general personal property but lack the specialized knowledge needed to value sports cards and memorabilia.

Once you find an ISA-accredited appraiser, make sure they’re also competent in sports collectibles. Find out if they appraise other categories or specialize exclusively in sports.

Fair Market Value: The Standard for Tax Matters

The IRS defines fair market value (FMV) as the price that property would sell for on the open market between a willing buyer and a willing seller, with neither person under any compulsion to buy or sell, and both having reasonable knowledge of all relevant facts.

This definition governs estate, gift, and charitable donation reporting. Fair market value is not the standard used for insurance appraisal reports.

Replacement Value for Insurance

Retail replacement values are used for insurance appraisals. These values are typically higher than fair market values because they reflect the cost of replacing an item with one of comparable quality in the current market.

The goal is to make sure the client is properly compensated by their insurance company if they need to file a claim in the future, subject to the terms of their policy.

The Tax Context: What CPAs Need to Know About Collectibles Valuation

When your client donates sports cards or memorabilia, the IRS has specific requirements for documenting the value of those collectibles. Here’s what CPAs need to know.

Qualified Appraisals and Qualified Appraisers Under IRS Rules

A qualified appraisal from a qualified appraiser is generally required when a person claims a noncash charitable deduction of more than $5,000. The appraiser must meet IRS qualification requirements and have the necessary education and experience to value the specific type of property being donated.

A USPAP-compliant sports memorabilia appraisal helps establish a credible, independent valuation that meets applicable professional standards.

Form 8283 and Charitable Donations of Memorabilia

If the claimed deduction is more than $5,000, the appraiser generally must complete and sign Section B of IRS Form 8283. A qualified appraisal report is also required.

For noncash charitable deductions between $500 and $5,000, taxpayers generally complete Section A of Form 8283.

Valuation Misstatement Penalties for Taxpayers and Appraisers

The IRS can penalize both the taxpayer and the appraiser if the taxpayer files a return with a substantially incorrect valuation and the appraiser is responsible for the faulty appraisal.

Penalties depend on the circumstances and the size of the valuation misstatement. This is why hiring a qualified, independent sports memorabilia appraiser is so important.

Collectibles-Specific Tax Considerations

Gains on collectibles held for one year or less are generally taxed as ordinary income, with a top federal rate of 37%.

Have a collection you want appraised?

No sales motive, no consignments, no conflicts of interest. Just an independent valuation from Michael Osacky.

Gains on collectibles held for more than one year, on the other hand, may be subject to a maximum federal capital gains rate of 28%, compared with the generally applicable 0%, 15%, or 20% rates for most other long-term capital gains, depending on income.

The Estate and Trust Context: What Estate Attorneys and Fiduciaries Need to Know

Estate Tax Reporting and Fair Market Value at Date of Death

When somebody dies, their estate or trust may receive a step-up in cost basis for inherited sports cards and memorabilia.

For example, the decedent purchased an item 40 years ago for $500. The fair market value at the date of death is now $50,000. The trust should hire an ISA-accredited appraiser to prepare a formal appraisal report using fair market value (FMV).

If the appraiser assigns a value of $50,000, that amount generally becomes the new cost basis for the inherited item. If the family later sells it for $50,000, they generally won’t owe capital gains tax on the $49,500 increase in value that occurred during the decedent’s lifetime.

This can save the family thousands of dollars in potential taxes.

Equitable Distribution Among Heirs

Unfortunately, death can bring out the worst in people. Heirs in disagreement are all too common.

A professional sports memorabilia appraisal puts everybody on the same playing field. When both sides know the fair market value of the collection, disagreements may subside, and cooler heads can prevail.

Fiduciary Duty and Independent Valuation as Risk Management

A USPAP-compliant sports appraiser must follow professional ethics standards and remain objective, without being influenced by greed or conflicts of interest.

If an appraiser also operates an auction house, there might be an inherent conflict of interest. It’s important to hire an independent appraiser with no outside conflicts of interest.

Contested Matters: Probate Litigation, Divorce, and Beneficiary Disputes

On rare occasions, an appraiser will have to testify in court. This may happen during probate litigation, divorce proceedings, or disputes among beneficiaries.

Make sure the appraiser is comfortable testifying in court from the outset of the agreement, and find out what this person charges. Testifying in court is expensive, so make sure to set aside some funds for this expense.

The Role of an Appraisal Expert Witness

An appraisal expert witness plays a crucial role in court-ordered matters. Beyond preparing a formal appraisal report, the expert may testify in depositions (usually via Zoom or phone), prepare for trial testimony, and respond to opposing arguments. An expert witness may also be called to testify at trial or participate in mediation.

One crucial task is reviewing both the appraiser’s own report and the opposing expert’s appraisal findings. Sometimes we forget what we said six months ago, so it’s important to review our own work before testifying.

It’s equally important to review the opposition’s findings so you understand what they’re trying to achieve and which points they’re likely to “hammer” you on.

If you’re hiring an appraiser for a legal matter, make sure they’re comfortable providing expert testimony and confirm their availability and fees before signing an agreement.

What Is a USPAP Appraisal and Why It Matters

The Uniform Standards of Professional Appraisal Practice (USPAP) establish the professional standards that appraisers follow when preparing an appraisal report. Here’s what CPAs, estate attorneys, and other professional advisors should know.

The Standards That Govern Personal Property Appraisals

The Uniform Standards of Professional Appraisal Practice (USPAP) are the benchmark for ethical and competent appraisal practice. The framework was developed by The Appraisal Foundation.

Ethics, Competency, and Scope of Work

Scope of work and appraisal objectives are among the first things an appraiser asks about. It’s important to hire an appraiser with competency in what you want them to appraise.

An appraiser specializing in Chinese ceramics may not be competent in comic books. It’s always best to find out early. All appraisers must adhere to strict ethics rules regardless of the appraisal objective.

What a USPAP-Compliant Report Contains

Each appraiser must include numerous items in a formal appraisal report. There is an entire checklist of elements that must be included. Some of the pertinent items are:

  • Intended use and intended users
  • Definition of value and effective date
  • Item descriptions
  • Appraisal methodology and comparable sales
  • Assumptions and limiting conditions
  • Appraiser’s qualifications and CV
  • Disclosure of any outside assistance used to complete the report
  • Signed appraiser certification

What ISA Accreditation Means in Practice

The International Society of Appraisers (ISA) has a very rigorous process to become an accredited member. It’s not an organization where you pay money and you’re in.

A candidate for ISA membership must understand appraisal methodology, ethics, demonstrate competency, and pass examinations. Once a candidate becomes a member, they have three years to advance to accredited membership. Members who fail to meet the requirements within that period may lose their membership.

An ISA-accredited appraiser is somebody who has both the experience and knowledge to accurately appraise personal property. For sports memorabilia, make sure that expertise extends specifically to sports cards and collectibles.

Frequently Asked Questions

Who counts as a qualified appraiser for sports memorabilia?

Under IRS rules, a qualified appraiser must meet specific education and experience requirements and have expertise in the type of property being valued. For sports memorabilia, look for an ISA-accredited, USPAP-compliant appraiser who specializes in sports cards and collectibles and understands IRS appraisal requirements.

Does donated sports memorabilia require Form 8283?

Generally, yes, if you’re claiming a noncash charitable deduction of more than $500. For deductions over $5,000, the IRS generally requires a qualified appraisal and completion of Section B of Form 8283, including the appraiser’s signature. Additional documentation may be required for higher-value donations.

Can a dealer or auction house provide a defensible appraisal?

A dealer or auction house may provide useful pricing information, but that doesn’t automatically qualify as an independent appraisal. For tax or legal purposes, it’s important to hire a qualified appraiser with the necessary credentials and expertise. An appraiser who also buys, sells, or consigns collectibles may have conflicts of interest.

Can a fine art appraiser value sports memorabilia?

A fine art appraiser may be highly qualified in their field but lack the specialized knowledge needed to value sports cards and memorabilia. Sports collectibles require an understanding of authentication, grading, provenance, market demand, and comparable sales. Make sure your appraiser has demonstrated competency in sports memorabilia, not just general personal property.
