Trust me, if it's been minted it's been faked. Companies like Provident buy and sell all the time. Not surprising that a fake or two could make it into the mix when buying from an outside source.
I can't even remember how many morgans, rolls of eagles, maples, kooks, pandas, libertads etc. I have sold to coin dealers who rarely even open the tube let alone measure, weigh etc. I don't care who you are buying from, you better be skeptical and check everything you get.
Buy Low Sell High
Keeping it simple with the Eagles, Maples and Krugs....
