Yep. AH1237 = AD 1821/22. Krause lists a 1/8th budju (~18mm, ~1.25g, KM# 74) and a 1/4 budju (~21mm, ~2.4g, KM# 67) with that date and denomination. CV is about the same for both denominations ($30 in VF).
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
