Do a search on Ebay to see if anything similar has ever been auctioned off before. The memorabilia market in general has collapsed. This would not be a good time to sell something. For instance I have seen an autographed Beatles gold record which at one time would have fetched close to $100,000 sell for less than $3000 and I saw a set of autographs from the Topps company (the baseball card people) of the greatest baseball legends at each position (Ty Cobb, Roy Campenella, Babe Ruth, Cy Young, Lou Gherig, etc) that was appraised for 1 million dollars sell for $11,000.
