How much is a pack of Washington Redskins chewing gum worth?

I too have a brand new pack of Washington Redskins Chewing Gum. I have searched and can not find it anywhere. I just acquired a pack of Baltimore Orioles gum and found that on eBay for about $ 6.00 plus almost $ 6.00 shipping. I would price mine at $ 10.00 in our store. I guess I would price the Redskins at the same or maybe $ 15.00 and let someone talk me down to 10-12. Hope this helps a little. I have searched for about 2 years now. Not many for sale, or not many left.
