I've got this fun little "Houdini Disk" trick:

...but I want to be able to do it with coins. I feel that real coins and a nice brass box would appear more substantial, and using something like two English pennies for the "guards", and a Kennedy half as the American "Houdini", would sell the story better.

Does anybody make something like this?

I think I can assemble the necessary parts using standard gaffs, except there might be trouble locating what would essentially be a "reverse" S&S set that would (mostly) self n***, and (ideally) hold up to at least cursory examination?

Any ideas / comments?

Here is a video demo of this nice effect:

Sounds like you're talking about "Coin Squeeze":

It has already been done in coins by Eddie Gibson. It is called the Copper Sandwich and was available in English or U.S. Coins.

I have "Coin Squeeze", and while it's also a penetration effect, the "Houdini Disk" is different.
I'd describe it generically as clearly/visibly/fairly placing three coins in an okito box which is then closed. The top of the box is given a magical tap, and one of the coins "falls out" through the solid bottom of the box. When the box is opened, there are only two coins found inside.

Thanks for the link. That's what I was looking for.
Now if only done up with two English pennies and a US half....
