After unpacking from my trip to Vegas last night, I found a stack of 18 Nevada Palace $1 21st Birthday chips. One of the chips seemed strange. I compared the one I was holding to the other 17 & there is a difference. The "error" has 8 stripes on the edge, & 6 rather than 8 dots. Could someone else who has these chips check to see if there may be others the same as my "error".
