Edit: I was going to start a "Follow the Leader" game thread based on my long-running Collectors Universe "Coin Uno" game (10 years and over 4K posts), but it looks like someone already posted a spinoff here. So never mind. I did just create a separate World Coins edition of the game, though, based on country or date rather than type or date. I'll leave that one up.
Really? I must have missed it. One of my Collectors Universe imitators must have posted it sometime after I joined here in 2007 and went dormant for so long. (But I consider imitation a form of flattery in this case.) In that case, never mind. I'll go look at the other one. What forum is it on?
That's good because I couldn't decide what to do about coins from sellers in china. Go by the date on the coin or last Tuesday at 2:00AM?
