The current federal status of this trademark filing is EXPIRED. They produced HANDBAGS, WALLETS, KEY CASES, AND COIN PURSES from the date of the trademark filing I would not classify this as an antique.
As far as value unfortunately not much many on ebay priced high but not selling, your style of bag is older and people just do not seem to be that intersted in allgator bags.Maybe $40.00 You could try ebay but I say keep it in the family and pass it on. Very pretty bag!!!
