It depends on if it is authentic. Proof of authenticity adds to its value, and allows you to sell the item on places like Ebay that will require you to prove its authenticity.
I agree that having proof of authenticity would add to the value of the card. However, there are many other places, other than eBay, where a person could advertise to sell such a card, and offer proof of the authenticity of it.
The sites listed below don't require any sort of fees such as eBay does and also get excellent exposure when people do searches for things on the Internet.
I think we are all so great to take care of others, however how can we learn to take care of ourselves more? What things can one do to take care of their own self-worth, self-respect, etc.
I have a 1985 circle K mickey mantle autographed baseball card and I was wondering how much the card is possibley worth. Or possibly where I can go to be able to find out if no one has an answer. Thanks
