$1 coins take two

As a followup to my last entry, I did an experiment on the work vending machines today. I am happy (and surprised) to report that both the candy and the soda machine happily took my dollar coin. Oddly enough, when I hit coin return they both gave me back four quarters!

  1. If I remember right, there was fun article about the squaw in one of the science rags. The mint needed it to be the same size as the Suzy BA coin and also share the same density and magnetic characteristics, while having a completely different color. Evidently, vending machines use more than just size and weight to check coins. It was a fair bit of alchemy to get the mix right right.
