My wife came across a coin the size of a dime. On one side it is a dime however, when you turn it over it's a penny. The thickness is similar to a dime I would guess. I'm not an expert, but we've looked it over many times and have shown it to a lot of friends and it looks like it was stamped that way. It does not look like anyone could have made it this way. Any idea if it's worth much or any interesting thoughts? Thank you.
Well, Heritage did auction a similar coin for $138,000 back in 2006: http://coins.ha.com/common/view_item.php?Sale_No=404&Lot_No=5271&type=top10-coinnews-tem090608&ic=
Yes, before we go scaring off a newcomer to the numismatic community we should definetely see a photo. More often than not it is probably a magicians coin but the chance is still there for a mule!
