Any ideas on this Spanish cob?
I was wondering if anybody could provide attribution information and/or a rough date range on this Spanish cob? It is not my coin, and not in hand. Nor do I know the diameter and weight yet, though I have sent a request for that information to the seller.
What I find intriguing is that it apparently comes with an old collection envelope, showing that somebody paid a dollar for it in 1943.
It looks like it might be pretty small, so I'm guessing a half-real, maybe? Or one real? There's that "I" on there. But from which country/mint? And when? I'm out of my depth here.
