Jim, an Oregon chip dealer has these and many other genuine old Reno chips available in very large quantities. They are shown at many chips shows in shrink wrapped rolls and it's not a secret they exist.

Not a new development, but one that many new to the hobby may not be aware of. All these chips were obtained legally and prior to the requirement for destruction of de-monetized chips by Gaming.

They do make nice home sets, as this eBay seller has shown.
