Here is an NCV I picked up at the convention. It's listed as N4868 in The Chip Rack. James' book lists it as always notched, and with some lettering frequently scratched off (as on this one). It appears that the management no longer wanted it played in the casino, so I guess this changes from an NCV to a No Value chip [g]. Half a buck doesn't seem like much of a prize for a Hole in One, even in the 1950's.

A note about these aspects of the chip might be nice to have in TCR.
