VINTAGE GUCCI WALLET

>>NOT FOR SALE at the moment. Hello! I bought this wallet about 8-9 years ago when I was 16. This wallet was sitting behind the counter at a thrift store. I purchased it for $20 not knowing if it is authentic or not. I've done a few research on real Gucci items vs fake ones. I feel like this piece is authentic but would like others opinion and try to collect any information on this wallet. (: thanks!
