Help to verify this coin.

This coin is 15 mm diameter and weight is 0,75 gram. Composition billon. 

It looks like a solidus from Riga with Christina as ruler ( N#41643 ). The problem is the date (16)60. Christina was ruler until 1654. The ruler in 1660 was Carl XI. Can anyone contribute to solve this mystery? 

Thank you in advance
