An autographed army photograph of Elvis Presley is valued by having the item officially appraised eitehr online or at a local appraisal venue. This allows for a more accurate estimate, since the value depends on several factors, including its year and condition.
Obtaining a Certificate of Authenticity for the item also helps to determine the value of an autograph. The COA is a document that authenticates the autograph to distinguish it from forged autographs. The document doesn’t always guarantee the item’s authenticity, but does add value if it’s from a reputable dealer.
In 2012, ElvisBlog.net reported that an autographed army picture of Elvis Presley sold for $2,375 at an auction.
