Where or how can you determine the value of some old 8x10 glossy photos of about 7 players from the 50's including Mantle and Robinson?

Answer 1

The most accurate way of coming up with a value is finding auctions where a signed photo of the ballplayer sold. Signatures will vary in price based on condition, the type of authenticity that accompanies the signature, the item signed, and how well the item displays the signature.Baseballs are the most common, and preferred by collectors because of it's connection to the game, low cost, availability and it displays the signature well. The signed Baseball represents the average price for a signature, and by deducting or adding from this price for the Item signed accordingly will give you a good idea on value.

The lowest priced signed item would be for a "cut Signature." A cut signature is a signature on a piece of paper, or "cut" from a larger piece. Index cards are the next step up, and both sell at a fraction (about 10%-20%) the price of an autographed baseball. Autograph photos typically sell at about 40-60 percent the price of a baseball with bats, uniform Jersey's and equipment selling at a higher price due to the higher cost of the item, rarity and display.

In general if an autographed baseball is worth $100. the same autograph on a 8x10 photo $50. a cut signature $20. on a bat $150. The percentage of the price could also vary based on the popularity of the player, and how sought after the signature is. A Mickey Mantle single signed baseball is worth about $400.-$600. A Mickey Mantle signed 8 x 10 photo is worth about $150.-$300. If you use the formula above you should have a general idea of the value of your 8 x 10 photos.
