Hi Pete, I have the one with the large square periods, so that should be the first issue.
Dot periods must have come later. As for myself I most probably wouldn't notice the difference unless I got both of them at the same time.
Most of the time back about 12 years ago we were lucky to get the casino personal to part with one 50-cent chip, so never had any number of them at the same time to compare.
Also I am begining to think we had more fun driving 2100 miles in three days to collect Mich-Minn & Wisc chips then we are now having driving 5 miles in Las Vegas.
