Okay, this coin squeeze is not like the one Penguin originally had. That one locked, but this doesn't.

Which means throughout the amazing effect where the coins penetrate through solid metal, you need to hold the apparatus together.

What I don't like is that only one coin can go through at a time, not all four coins. It's examinable to some extent, but not thoroughly.

But for this low price it's not half bad. It's a neat pocket trick, but not something I do often.
