Which references do we use to value a coin collection in Virginia?
The PCGS and NGC price guides and realized-price archives from major numismatic auctions such as Heritage, matched to each coin's grade and variety. Grade, rarity, demand, and provenance drive value far more than date or face value, so a defensible report documents denomination, mint mark, variety, condition, and authenticity coin by coin.
Does cleaning old coins hurt their appraised value?
Never. Cleaning, polishing, or otherwise mishandling coins is one of the most expensive mistakes owners make, because it permanently damages surfaces and can cut a collectible coin's value drastically. Bring coins as they are, in whatever holders they occupy, and let the appraisal document condition exactly as found.
Will Virginia tax an inherited coin collection?
No, Virginia imposes no estate or inheritance tax; the belief that it does is a common misconception. Federal filing is a separate question: when a gross estate exceeds the federal threshold, coin collections are reported on Form 706 at fair market value, which is where a documented numismatic appraisal earns its keep.
Why can one grading point change a coin's value so much?
Because collector demand concentrates at threshold grades, a single point on the Sheldon scale, such as the jump from AU to Mint State or MS65 to MS66, can multiply the price of the same coin. Rarity is properly measured by how many examples survive at a given grade, not by mintage alone, which is why we match comparables grade for grade rather than quoting a series average.
