Yes, big time. They sell them on the markets on DarkNet. Most of the fakes are 10 oz Engelhard bars. If I buy bars now I stick to Sunshine that has the mintmark SI security feature.
Good to know. I’ll have to check my inventory. I wonder at what point they get caught in the buyer/seller chain. In my area I have not heard of many turning up. Maybe it would be better buying dime/quarter/halve junk silver or alternatively buying directly from the mint?
