Just cracked open a mint sewn bag of Bison nickels I had sitting on shelf in garage(inside) since March.
Had kept them in sewn bag inside mint sealed box. Some are definately showing early golden/purple toning. Bag? Cardboard?? Cardboard glue?? Car fumes??
I wonder what these bags/boxes will do to coins in 5-10+ years.???
