Found this coin fairly close to where I live. Added another 90 miles to the mileage of Erin's coin by bringing it to Norrköping. Pity I didn't notice this coin a little earlier, because then I could have brought it to Spain. Anyway Erin; your coin's mileage is way ahead of your sisters. Even if you add up Kriss' , Kellies and Alyssas mileage together, it still doesn't match Erins.
Your coin is now in a cache hidden in a churchyard stone wall in Norrköping.
