:Yeah, and of course its issue is not the same as its country of issue, and it was that kind of thing that I didn't want to confuddle the Helpdesk answer with.

I think, also, Euro coins are mostly minted by the Royal Mint, well they do about 1/3 of the world's coinage and certainly had the die-stamps in place to do it before it was introduced (I'd have a hard time I guess tracking that citation down), and since you only need a different die-stamp for one side, makes sense to make them all in one place.

One thing I'm interested in, as a minor hobby, is the butterfly effect on Euros (not sure if that is quite the right phrase). My guess is that small coin tends to stay fairly local whereas larger coins, and notes, circulate more widely. See my PhD grant "Effects of Euro standardised coinage on the Butterfly Effect". Did I say "see"? I meant "fund".
