you'd get them, but it is definitely illegal. Fakers do coins because they are ridiculously easy to forge compared to notes.
You might be able to get away with it in shops, but banks would pick up on it. Not worth the trouble, I say.
Edit: and the "coins for sale" posters on his stool look like they've been put on with paint or something - there's no way the police would let him get away with that.
