I can make out the tail of the kangaroo in the palm stamp, so this is an AMG 175k. I'd imagine a fair price for this glove, in this condition, going for $60-75, maybe more with a re-lace and a thorough recondition (Lexol orange and brown, and your favorite glove conditioner afterward). A pic of the finger backs and hand stall could help confirm what it could go for.
Good luck with sale when you decide to put it up for sale.
