Interesting and very nice imitation / forgery of the era modeled on the Lublin issues.
The result of the work, however, far removed from the original ;). Lublin is indicated by the Axe mark (placed on Lublin trojaks in 1595), but here surrounded by an abbreviated, fancy date (0-8), without, among other things, the Treasurer's coat of arms or another portrait on the obverse.
A rare item.
Silver (of lower grade), diameter 21 mm, weight 1.91 g.
