Russia-Sweden, Copper Token 5 Kopecks 1840 with Swedish Crowns, 28.66g/56x63mm
Unusual cross-regional copper token, countermarked "5 K 1840" on a copper plate bearing clear Swedish triple crown punches, indicating the reuse of earlier Swedish copper, possibly from plate money. Weighing 28.66g and measuring 56x63mm, this enigmatic piece likely served as a low-denomination payment token in a military, mining, or trade context along the Russian-Swedish borderlands, possibly Finland, which had been ceded to Russia in 1809 but retained strong Swedish cultural and administrative influence. The initials "JJ" may refer to an official or inspector. From an old Swedish collection.
