You don’t have to be a magician. I was impressing other kids doing exactly this, you just toss so the coin goes high but turns slowly and catch it in your hand rather than let if fall to the ground. After not so many tries you get a pretty good intuition on how you have to throw to get the desired result.

There's also a particular method to get the coin in a tilted spin that looks (and sounds) _remarkably_ like a real flip, and is I think going to be more repeatable than what you're describing.

It works the other way around, this kind of trick is (stage) magic so if you're doing it, hey presto, you're a magician.
