YEAR NUMBERS ON COINS OF CAPPADOCIA AND OTHER CITIES.

• The following list translates examples of e.g. the regnal year as shown on a coin, into the actual number.
• The actual date differs of course from emperor to emperor.
• Consular (COS) dates (shown with YΠAT or YΠATO etc on the coin) are not the same as regnal years (ET or ETOYC etc). Consular terms could often last for several years.
• Note that some date marks were engraved in a manner that appears to us to be the wrong way round, e.g. ΔI instead of IΔ. This does not constitute an engraver's error, as there was no firm and fast rule about how such dates should be engraved, as e.g. 4 + 10 (ΔI) or 10 + 4 (IΔ).
• The 6th letter of the archaic Greek alphabet (digamma or wau) can be seen in three forms, one of them resembling a Latin F and which was the ancestor of our letter F. You can see it in the table below.
