Now that you mentioned it, I also like picking up Coins when I Travel... I picked up a "1913" $5 U.S. Gold Coin when I was in "Old Town" Prague... It's in a High Mint State Condition... I paid 182 Fiat USD's for it, and brought it back to the U.S. with the rest of my Coins... I think it's currently worth over 50,000 of today's Fiat USD's...
