This Expanded Shell contains a Steel Shim which is recessed into the inside bottom of the shell so that is does not reduce the coverage over another inserted coin. The advantage of the steel shim is that the shell can be stolen/removed from the nested coin with a magnetic PK ring etc.

Expanded Shell Sets use an expanded shell along with ungaffed inner coins which are hand-picked for an exact size-match as well as for overall appearance matching. With expanded shells, it is possible (with some searching) to find other ungaffed, matching fits. An expanded shell might also fit your other normal-sized gaffs, like your flipper coin.

These shells are manufactured by Roy Kueppers. I personally manufacture each item that I sell and I use my very own unique method for Expanding shells. I also very carefully select specific characteristics in the coins I choose to make the shells. Not all coins are created equal so I feel that a combination of the right chosen coin and my unique process make for a high quality Expanded shell with 90% coverage when nested.

Many effects are possible with the use of this shell.
