There are a few sets around. I have one of the bigger cash sets and maybe the only full dovetail rack in existence.

The other two guys have had those sets for years. They are around and can be made

There are alot of chips I think still in the vault. I only know of 3 big cash sets, two or three big WSOP sets.

But yah WWalker has dug up some insane stuff from estate sales.
