I was visiting the Pohjanmaa museum at Vaasa/Vasa when I saw a coin I have never seen before, a 2 ½ Öre coin. The collection on display with coins from Sweden, Finland, the Russian Empire and Georgia had belonged to Mauritz Hallberg (1851-1924). I do not own any catalogs so I don't have a lot of information on the coins not on Numista.
I'd appreciate it a lot if someone could tell me about this coin, because it currently isn't on numista.
