The coins look, feel and sound amazing.
They are not very thick so easy to palm.
Weight is substantial so will feel great if you hand it to the spectator.
I had to file it a bit around the edges to remove sharp corners, so I know it's chrome coated brass, at least from the looks. Which also means it won't rust.
The only complaint anyone could have is that they easily dent if dropped from 3-4ft. So don't drop them I guess...
