Anyone know of a book or pamphlet listing old powder cans, dates, value, etc? I have about 25 of them sitting on shelves in my loading room. Most are from the 50's, 60's, 70's and are powder I bought for reloading. They vary from full with seals, to partial cans, to empty. Not looking to sell, just looking at them as a small collection or display. Some are fiber board, some metallic, from back when not everything came in plastic. DuPont, Hercules, Alcan, Hodgdon, WW, Bonanza, etc. Thanks. GJH
