Yes, also note that I am a lefthander. If you throw with the right hand you will
get totally different results of course. You also have to throw the coin
reasonable high. As everyone knows the results of those short throws are totally
meaningless. Only bean counters are doing this to be able to throw the coin as
often as possible in a short time. And: never change the coin within a series of
throws. After about 5 throws you should make a short brake because otherwise
your hands temperature would influence the result of the match too much.

It would be interesting to make a round robin tournament between all kind of 2
Euro coins.

Best wishes,
Steffen.
