Despite what you may think I have had little luck at European flea markets or antique stores. On my two week trip I think I found a total of 4 or 5 chips at various places plus a box of MOPS at the Paris flea market. I did get a lot of current stuff at the casinos but I was mostly driving during the day and casino hopping at night. It sure was fun though. On our trip through central europe I also had lots of free time at night and hit every casino I could find.
