There's a head scratcher
Different I'll say, although. I have in my collection a couple of UK 3pence coins from the same time frame, and they are similar in appearance and size. I feel they may have been used by troops during WW ll in Britain as a badge or medal for identification or for God knows what Just a theory, it just could be something simple
I wonder if anyone else out there has any other early 40s coins drilled out like that
