A neat and tidy little series.
My very first ancient coin was a Divo Claudio from this series. Tiny little thing. It was identified by the coin dealer (the coin department of Sears Vancouver) as "Ancient Roman, 100-400 AD"; I didn't find out it was a Divo Claudio until I bought my first Sear catalogue, a couple of decades later.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
