You're right, there's a ton of this stuff "out there". I remember Frank Roza, a Reno and Carson City
coin and chip dealer, showing me multiple boxes of uncirculated hot stamp yellow $5 New China chips.
I bought boxes of large crown Ta Neva Ho $5, $25, $50 and $100 plus 3 or 4 boxes of the $5 Noll
chips from him. I remember hauling 5000 $1 Crystal Bay chips to Las Vegas and selling them to a
dealers school for Frank. Years ago there was a ton of Mapes and Nevada Club chips around. I remember a dealer selling them by the tube at one of the conventions.
