1 Ducat - Carl XI Trial strike

Narva in 1671 was a Swedish-controlled Baltic trading city, and this trial strike almost certainly relates to the city's periodic attempts to secure minting rights under Carl XI's administration.

A silver trial in ducat diameter suggests the city was pitching a specific denomination for approval — the use of silver rather than gold may indicate a cost-reduced proof of concept submitted to Stockholm.
