P Please tell us more about how the Swedish government got involved with the production of counterfeit copper 5 kopek in 1780s. Also, is the cross to which you refer on the reverse near the centre ? I am not sure I am looking at the right thing.
I should have mentioned that this is my understanding pf the counterfeit 5 kopek story. When Gustaf III invaded Russia in the Russo-Swedish war of 1788-1790 he needed Russian coins to pay Russian workers in the border regions. He came up with the idea of having the Avesta mint strike 5 Kopek copper coins like those of Tsarina Catherine II. The Swedes claimed that they had captured the copper coins from Russian ships.
Here is a coin from my collection Karl XI 1665, 8 Mark. One year type. 15 specimens known in total and just 4 of those of this particular dye number 4. This coin being the finest of the 1665 issue.
Coins of KARL X GUSTAV (1654-60) Karl X Gustav, named heir to the throne by the childless Queen Christina in 1649, was the son of Johann Casimir, Count Palatinate of Zweibrücken-Kleeberg, and Catherine, daughter of Karl IX of Sweden, and brother of Gustav II Adolf (and for some years guardian of his daughter Christina). When his father died in June 1652, Karl X Gustav inherited his lands and title and added the Palatinate arms to his Swedish arms. 1/4 öre 1657 Riksdaler 1657 and a coin from one of Sweden's German possessions POMERANIA Taler 1655
