Catherine II "Cipher Series" Kopeck 1796 XF45 PCGS, Brekke-10/11 (Extremely Rare), Bitkin-943/944 (R3). Obv. Crowned monogram of Catherine II. Rev. Date and value. Overstruck on an earlier Denga, with a considerable amount of the undercoin showing on both sides. The edge is straight reeded, therefore, this must be the original coin edge, and it must have been struck over an Ekaterinburg mint coin, as this mint appears to have been the only one to strike a Denga with a straight reeded edge. The strike is crude, with most details bold despite the overstrike. The first example of this ultra rare type we have seen.
