Reminder: Chinese has Two Sets of Numerals ("Banking Numerals" or "Safety Numerals")

壹、貳、叁(参)、肆、伍、陸、柒、捌、玖、拾.

Several of these numerals have multiple, alternate forms: there is definitely a form of 貳 in use that just has two lines in the bottom-left corner, for example, and and 叁 can be written as 参, etc.
