Your post intrigued me - I wondered how many I had. I have - or more correctly - had - the 11 shown below. I traded away that beautiful Pioneer chip a long time ago. Since I only collect Northern Nevada chips this may be a good sample - I know I need the matching 10 cent chip from the Cal Neva - but I just don't know how many others were made. I do have an extra of the King's Castle 50 cent chip if you need it. You will sure have a great collection if you can get them all!!! Good luck and happy hunting....
