Although the actual edge lettering looks somewhat different from the artist rendering of this edge lettering seen in the previous image, I don't think anybody could have anticipated the reality we got when the first Washington Presidential Dollars entered circulation. Hundreds of thousands of Presidential Dollar error coins were discovered with a variety of error types befalling them, but the most notorious were the so-called "Godless Dollars," where the edge lettering was left off of the coins completely.
The edge lettering on these circulation quality Presidential Dollars can begin and end anywhere around the circumference of the edge, and the lettering can appear right-side up or upside down in relation to the heads side of the coin. It is not an error if the edge lettering is upside down, or starts at the bottom, etc., on normal coins. However, on Proof Presidential Dollars, the edge lettering should always be right-side up and start in the same place on each coin.
