I have a chance to acquire a 1974 Topps Al Kaline Autograph certified by GAI. Do you guys think that I would be able to trade it here at THE BENCH without much problem,.......what I mean is, is GAI a reputable enough company that collectors wouldn't value the card down because it is GAI and not PSA/DNA certified. Also, what kind of trade value do you think I would get for it? The auto is in black sharpie and it is very solid and clean. Thanks in advance for your opinion.
