There are as many fake gold and silver coins as real ones. At one of the big coin shows this year they found fakes all over the show. If someone I didn't recognize like Mark dice came and did that to me, I'd assume it was fake. I'd give him a candy bar for it to go and check, but I'd pretend it was a lottery ticket that will probably not win. However, If I ever see MD I'm going to mosy nearby and hope to God he grabs me.
