Hello Mr.Sanchez..I noticed you have posted a comment on my video about fake autos and your concerns about your item....G.A.I is not around any more and now are called G.A. they went out of business or went bankrupt...your best bet may be to post pictures of your autographed item and get opinions from some other collectors and they may be able to help you...as far as G.A.I a lot of there's stuff authenticated were forgeries...but not everything...It wouldn't hurt to get a second or third opinion on the subject or you item...I personally try to stay away from there items but have noticed lately that G.A. has authenticated some authentic Mantles and Jeters that were good pieces in the market
