FAQ
Sports Memorabilia Appraisal Questions
What types of sports memorabilia do you appraise?
We appraise a wide range of sports memorabilia and collectibles, including autographed items, vintage cards, game-worn equipment, jerseys, photographs, and other pop culture collectibles. If you're unsure whether your item qualifies, contact us with details and we'll let you know.
Why do I need a professional appraisal for my memorabilia?
A professional appraisal establishes fair market value for your collection and is essential for several purposes:
- Estate planning and probate documentation
- Charitable donation deductions (IRS Form 8283)
- Insurance coverage and claims
- Divorce and equitable distribution
- Loan or collateral documentation
Our appraisers prepare reports in accordance with USPAP (Uniform Standards of Professional Appraisal Practice) so your valuation is defensible and recognized by tax authorities, insurers, and courts.
Are your appraisals USPAP-compliant?
Yes. Every appraisal we prepare follows USPAP standards set by The Appraisal Foundation. This ensures your report meets professional standards and is suitable for IRS filings, insurance claims, legal proceedings, and other formal purposes.
What credentials do your appraisers hold?
Our appraisers hold credentials with leading organizations such as the ASA, ISA, and AAA. We also maintain expertise across sports memorabilia, collectibles, and related asset categories. Every report is prepared in accordance with USPAP, regardless of the appraiser's specific credential background.
Do you offer free estimates or preliminary valuations?
We provide USPAP-compliant appraisals only. We do not offer free estimates or informal valuations. Our appraisals are comprehensive, standards-based reports prepared for a specific intended use. Contact us for pricing information and to discuss your appraisal needs.
How long does an appraisal take?
Turnaround time depends on the complexity and number of items in your collection. Single items are typically completed in 7 to 10 business days; larger collections generally run three to four weeks depending on the research required. We'll provide a timeline when you request an appraisal, and if you are working against a deadline (an estate filing, insurance claim, or sale), we'll confirm whether we can meet it.
