I was gonna post these as a "For Sale ad," but I will accept the values listed for most of the chips lol. I'm sure there have been plenty of weights listed in the past, but it fascinates me that chips from the same manufacturers can fluctuate so much due to several factors. Those factors include date produced, materials used, mold, wear, color, and inlay or stamp weight. Hotstamps are generally much heavier, take a look at the two identical Nevada Club pink quarters, the one appears to be stamped twice and is in better condition. I guessed on some of the molds/ names, feel free to help me out here.
