Description

The 1837 Christopher Bechtler Two and a Half Dollar Gold Piece with 64 grains and uneven "22" carats is the companion variety to the even "22" issue (PCGS #10076). The "uneven" designation describes the irregular spacing of the numerals "22" in the carat mark on the reverse die, where the digits appear unevenly placed compared to the balanced arrangement on the even variety. This distinction, while subtle, is a well-established attribution point in Bechtler numismatics. Both the even and uneven 64-grain varieties were struck during a period when Christopher Bechtler was actively adjusting his coinage specifications. The shift from 75 grains at 20 carats to 64 grains at 22 carats maintained approximately the same intrinsic gold value while using a finer alloy. This higher fineness resulted in a slightly different color and hardness compared to the earlier 20-carat issues, as 22-carat gold contains less copper alloy than 20-carat gold. The multiple weight and fineness combinations found across Bechtler quarter eagles — 64, 67, 70, and 75 grains at 20, 21, or 22 carats — reflect the pragmatic approach of a private minter operating in an evolving monetary landscape. Each combination aimed to provide coins with appropriate gold value for their stated denomination while accommodating the varying purity of gold delivered by local miners.

Rarity Notes

Scarce. Estimated 35-50 surviving examples. Approximately equally available as the "even 22" variety.
