believe $2.50 - $2.75 (good condition) is premium for these.
Given the market prices for other Paulson non-casino chips produced on less-desirable molds in much larger quantities (Classics, Casino de Isthmus, Pharaoh's Club, National Poker Series, etc.), I think your estimated value is extremely low. The Paulson Grand Cardroom solids were a very limited run, and sold for close to your 'premium' prices long ~before~ the market exploded -- and when the more common chips were selling for only $1 to $1.25. This would indicate that they are now "worth" close to $4 each or even more, and that's IF you can find any for sale at all. There is currently a
BCC spotted GCR set being sold at auction, and the current high bid on those is $2.16.
The Paulson GCR solids have always commanded higher prices than any other chip (regardless if inlay or hot-stamped) produced on the card pips (suits) mold, including the Pharaoh's Club NCV, Paulson World
THC, Private Cardroom, and Avalon Club chips.
I'd put premium prices need to pry chips out of an existing set at between $5 and $6 each, and you may not get any takers even at that level.
