What is the value of a Sharpie signed Mickey Mantle photo?

Nothing. The Sharpie type of pen was NOT invented until AFTER Mr Mantle DIED, so he could NOT have signed that one. Mickey Mantle was alive, and well in the late 1980s when he signed my Black & White Photo in Sharpie. I will include a link for you to see. You will also find information on what it's worth. Authenticating the signature will raise the value. PSA/DNA is one of the top authenticators in the business. The original Sharpie marker was first introduced in 1964 and has since expanded into a wide product line. Today, Sharpies are sold in seven varieties, according to the shape and size of their tip(s), ranging from "Ultra Fine" to "Super Bold". They also come in 34 ink colors.....

Price will vary based on condition, and the type of authenticity that accompanies the signature. Photo composition, and appeal will effect the price as well.
