Can I get any information on this baseball card?

I have a 1984 Donruss Diamond Kings card,


It's Mike Schmidt,


Autograph is on it,


in blue ink,


Number 23,


Has a red and blue banner above his head.





I am just wondering how much is this card worth?


I bought 10,000 baseball cards from a yard sale and this was one of them,


any idea and any information about this card?|||The card itself is not worth that much. In the 80's and 90's, baseball cards were way over produced, which means it is not worth a lot.





Now the autograph on it may be worth something, but without any proof or certificate of authenticity, it is not worth anything. If you send it away to be authenticated and it is a real autograph, it would probably be worth in the $60-$100 range. The fact that Mike Schmidt is still alive and signing at baseball card shows (mab-celebrity.com) and is charging $69-$99, that will tell you it is not worth going through the expense of getting it authenticated.|||Scrutinize the card back for a copyright date. If it reads 1983 or 1984, it's original vintage from the 1984 set. If it is more modern -- late 1990s or early 2000s -- it's a reprint, especially made to be autographed by Schmidt and inserted into pack product. This was not so uncommon around ten years ago.|||It's not certified so it's worthless. Is the card number 23 or did the peson write it becuase Schmidt was number 20.





Keep in mind the first guy Chris L guesses on every single one of these questions - he has yet to guess correctly. I have no idea why this nimrod just comes in here and guesses and how that helps anyone.|||Maybe $30. maybe
