An exceptionally interesting item.
Forgery or imitation from the era of the royal denarius of Boleslaw II.
Completely different in style, as can be seen especially from the royal portrait.
Very rare.
While denarii from this reign are regularly encountered in trade, this is the second time we have seen a counterfeit from the era.
Silver (lower grade?), diameter 12.3 mm, weight 0.38 g.
