Numista shows a listing for a Denmark coin and a Norway coin that look identical to me but with different km numbers. Help - what do I have here? Either way happy for under $5. 11.49g
The rosettes on the Norwegian reverse are normally smaller. It was minted for 1 year only, whereas the Danish mint produced them for 15 years with the date frozen at 1771. I don't know if yours is severely worn at the bottom of the reverse, but there should also be a rosette beneath the date.
I suggest you visit 1771skilling.com There is an amazing amount of information on this type coin on this site.
Ok for some reason I find it funny that there’s a website dedicated to exactly this question. Thanks. It’s a Copenhagen coin. Much appreciated.
