Lambskin Leather Vintage double C wallet

This is a beautiful vintage lamb skin leather wallet, it has double c logo but not sure if it’s authentic Chanel or not, it is excellent quality and condition with French purse/coin purse feature and many credit card slots and bill section, the lining is leather and a silk fabric and the coin purse gussets seem to be canvas, a unique piece, I’m guessing 1970’s or 80’s
