This is perhaps one of the most fascinating error types among the major Presidential Dollar errors. This coin, discovered by Shawn and Shelly Bell, was the first of maybe half a dozen of its type to emerge in the 8 or 10 weeks following the release of the Washington Dollar. The coin made a presumably normal trip through the Philadelphia Mint until it got to the edge lettering station. For some reason, the coin went past the edge lettering die twice, resulting in two separate sets of inscriptions around the edge of the coin. The Bells found this coin fairly early in the Washington Dollar error-finding frenzy, and they went on to discover a number of other interesting errors, which you'll see later in this photo gallery.
