Um, not to contradict one of our beloved leaders....

but....

I have to contradict what Arby just said. When you drop in more than 50 tokens they come out because they never make it into the hopper. If you somehow signal that a coin went in (like with an electronic device) but an actual coin didn't go in, then an actual coin will not come out. The hopper would have to active to spit it out.

So like others have said, more than 50 (or 53) just doesn't do anything. The coin pass through device opens, but since no actual coins are being dropped in, no actual coins come out.
