I have this happen a lot when tossing on wooden floors with a gap between the boards - basically the coin gets stuck in the gap. My brother and I got quite good at deliberately doing this.

I have never had it happen on a flat surface and I must have tossed 10,000 of coins in my youth.

I once attempted to hand a quarter to a convenience store clerk. Somehow we dropped it during the exchange. The coin rolled about 8 feet and went thru a tiny gap between two large cardboard boxes on the floor.

I'm sure I could have stood there for an hour attempting to drop a coin onto the floor and have it roll into that gap, and I would have failed.

I had a similar situation in which a coin I tossed managed to end up stuck in a small gap in the celling. I remember having to get up on a chair on top of a table (I must have been under 10 at the time) to get it out. Good times :)

The same is true for every possible outcome, that one just happened to be memorable.

If the odds of landing on an edge are 1 in 6000, it's not particularly unbelievable that you wouldn't have seen it in 10,000 tries. The odds of not seeing it are about 18%.

I saw a coin land on edge once.
