These three NCV Free Play chips are in current use, and are given out as bounce back promo or purchase with TR points.
Note the Year of the Ox has been out the longest (Rincon).
The So Cal has been out a year or so.
The WSOP has been out less than a year, even though it says Rincon.
Probably recycled from their WSOP Circuit events.

Asking $12 post paid to USA for all three.
Shipped in bubble envelope.
If you want only one or two, let me know which chip(s) and next trip I will try to get them.

Thanks.
