Two Heads Better Than One ... With Coins, Maybe So

Generally when you find expert comments on two headed or two tailed coins, the point is made that they are all fake, such coins have never come from the official U.S. mint but are put together in machine shops. Well, I found a site with information somewhat to the contrary. Perhaps the official mint actually did produce a few two headed or two tailed coins ... however, they never reached general circulation and so won't be found in your pocket change.
