Kopeck - Peter I

Peter I's wire kopecks — the last series struck by the archaic chekanka method, hammering slivers of silver wire between hand-cut dies — were officially discontinued in 1718 in favor of milled coinage. The 1716 issues fall within the final years of this medieval technique surviving into the eighteenth century, a production method Peter himself had already rendered obsolete by reforming the monetary system in 1704.

Cross-referencing GKH and GKH2 numbers on these is genuinely useful: Ilyn and Petrov's successive catalogs frequently split varieties that earlier scholars lumped together, and the wire kopeck series is particularly prone to die attribution disputes given the irregular flans.
