Post Your: Low-Mintage, Obscure, NIFC, Commemorative World Silver Coins

I'm a big fan of world silver coins; the art and history and geography appeal to my inner nerd and the silver appeals to my love of all things shiny. I have an admirable type set of circulating world silver, but I also enjoy low-mintage, obscure, not-inteneded-for-circulation, commemorative silver coins that only a collector could love. I'm talking about unusual pieces from Alderney or Pitcairn Island etc etc. I won't cal them rare (limited availability is usually a function of limited interest), but I will call these coins uncommon.
So, can we please post some low-mintage, commemorative world coins?
Silver preferred, and the bigger the better, but I'm not picky. Just looking for obscurity really.
Don't care much for the bulky presentation boxes, but post 'em if you got 'em!
PS: bonus points if you remember how much you paid or how much the coin is worth.

Not silver but definitely obscure (technically not even a coin-it's a fantasy pattern-but it counts for me
