引用する: kuba997I have IOM KM# 34.1 1979 with round logo (triskeles, no mintmark).
Can someone add it to catalogue?
Thank you!
But there is a mintmark; the PM (Pobjoy Mint) and the AD letters on your coin (map lower left).

So it goes on that page in 1979 AD surely. I don't know what the KM# 34.1 means - never heard of it, unless it means addition of that circular logo.
