All 1798 $10 gold pieces are overdates. Two varieties comprise the entire mintage for the year and both share the same reverse die. The difference between the two varieties is the placement of the stars: one has four on the right side of the obverse (BD-1); the other has six stars on the right side (BD-2). BD-1 is relatively common, though any coin with an estimated population of 100 pieces is a classic, American rarity. Mint State examples of this variety are very rare, and are led by a Gem example that was once in the Garrett Collection and which now resides in the Harry W. Bass, Jr. Research Foundation Permanent Collection of U. S. Gold, Patterns and Currency.
