Signature Value Guide
A signature's value is determined by a fascinating mix of historical significance, rarity, condition, and market demand. From presidential signatures worth six figures to celebrity autographs selling for a few dollars, the spectrum is wide. This guide explains the principles behind signature valuation.
Historical Signatures
Signatures from historical figures command the highest values in the autograph market. Presidential signatures range from $500 (modern presidents) to $500,000+ (George Washington, Abraham Lincoln). Scientific and literary figures like Albert Einstein ($20,000-$100,000+) and Mark Twain ($5,000-$25,000) are also highly prized. The key factors are historical importance, document significance, and survival rate.
Celebrity & Entertainment Signatures
Entertainment signatures vary enormously. Current celebrities: $20-$500. Classic Hollywood (Monroe, Dean): $2,000-$50,000+. Music legends (Beatles, Elvis): $1,000-$100,000+. The entertainment market is more volatile than sports, with values often tied to cultural relevance and nostalgia cycles.

How Rarity Drives Value
Rarity is perhaps the strongest long-term value driver. Signatures become rare when the signer dies, was famously reluctant to sign, or lived in an era before mass autograph requests. Players who died young (Roberto Clemente, Thurman Munson) or who rarely signed (Sandy Koufax in certain eras) command outsized premiums due to limited supply.
