VINTAGE Gucci Gld SnakeSkin Bamboo WAIST BELT PLSE HELP ME AUTHENTICATE.

I am hoping someone can help me authenticate this belt before I put it up for sale. I bought this many years ago between the years of 2010 and 2012 . I don’t exactly remember it could be even before . I bought it online from eBay for a bit less than 400 dollars. I do remember confirming at the time that it was authentic from the seller himself or herself. When it was sent to me , it did come with its own dust bag and it was neatly bagged. I don’t remember wearing it at all . I just want to confirm that it is authentic before I put it up for sale. If you know how can I authenticate it please let me know. Thanks in advance…
