Hi Rob, thank you very much for your reply, which, as always, is very detailed.
I’m attaching a few photos which I hope will help to determine the correct classification. If it’s of any help, there’s a rust spot (or at least I think it is) in exactly the same place where I’ve noticed it on other P-1242s.
Given that this is a late SOHO, is there a time frame within which it might have been minted, even if it’s just hypothetical??
