This could be expensive, Herc. After each flip, on average half of the remaining people will fail to match your flip, and will be eliminated. So if you start with a cast of one million, which is about 2^20, you run out of tossers after about 20 flips. You need to start with about 2^100 people to give yourself a reasonable chance of a match. Where are you going to get 2^100 coins? That's 12676506002282294014967032053 Euros and 76 cents!
