As I recall playing 21 in Korea, the minimum is 10,000 and multiples thereof. Thus, there are no snappers or even 500s. Some casinos in France also have a 10 euro minimum, and once I got my hands on a few 5s, so I tried to wager 15. The dealer threw the 5 back to me, and said bets must be 10, 20, 30, etc. Do I remember correctly, Lyle?
