Hi Louise,
Congratulations for finding the chips. As others have suggested, the value of these chips is greatly reduced when a box or more is found. However, a box of 100 is not that great when there may be over 100 collectors who may want one at a reduced price. The answer is whether you want to turn them over quickly and accept an offer such as Pete's or sell them over a period of a few months and get more for them. If you are in no hurry, I believe that you can get about $10 each by offering them on this board. If you are in Las Vegas June 25-28, come to the Tropicana for our annual chip convention. There will be about 150 chip dealers set up at tables. You could walk the floor and test the waters.

You have been perfectly honest with us by disclosing the amount of chips that you have. Good luck and have fun!
