How much is the NBA star signature card worth?

First of all, let me explain a few points. Your "signature of NBA Lakers center George Mikan released by 1948" is a joke. In fact, it should be signed by TOPPS at 1996, but it is a reprint of 48-year Mikanka with a signature. This is still valuable. After all, Mikan died, probably in 65438+. O 'Neill never signed a contract in 1997, so he can't tell which one you are talking about. Similarly, Duncan did not issue a jersey card in 1997. I guess you made a mistake. However, if it is the sign of Aopang in earlier years, it will be about $70 in 2000, but it is probably much worse in different series; Even if Duncan's jerseys are earlier, they are generally within 100 yuan (RMB), and some series are above 200 yuan. If you have a card, you can go to the most authoritative forum in China at present, ABC2, Baidu yourself, and don't let the website be sent.
