You have it. It was in the group trade eventhough not marked on the spreadsheet. It's shiny copper if that helps you track it down.
I haven't any shiny copper version in my clollection. I have 33 versions now, but not Georgia.
Emma wrote me, that Georgia joined the trades very late after the international coins were sent.
Oh, that explains why I had an extra coin, because I was missing a trade coin.
