Interesting, but also if they used a base-10 positional system, wonder why some had 12 (astronomically speaking 13 periods of 4 weeks makes more sense than 12 months)?

Used for tax obligations. Lets send some to all those Citizens United defenders. They may be able to count properly with these. Anyway, thanx Marty. Another fascinating artifact.
