Iceland 10 Aurar Cu-Ni '46-'69

I always thought this coin has regularly fine edge milling and on 1969 it was changed to coarse just like on Al coins.

But I am wrong now when I checked my examples. It seems all have coarse milling but some of 1969 have really fine, shallow with more denticles. As I do not have that fine milling can anyone confirm than coarse milling is normal for all the years? Since coins are very small it's not so easy to deduct that from the photos.

Thank you.

I have documented it only for 1969!

Only the 1969 has both!

Thank you Ole. Can you check and confirm please the older ones are coarse. When I take a photo and compare it's more similar to coarse but it's hard to match the lighting.

Yes, all the older ones have coarsed edges.

Thank you very much for confirming
