Random title: 1-O-V or 2-R-III or similar
Explanation: These odd looking notations look complicated but are actually quite simple. They are used as a numbering system for doubled die coins. The first number is the number assigned to the die. The letter in the middle will be either an 'O' (obverse), or 'R' (reverse). The third item is the class number, i.e. the type or cause of the doubling. It is noted by using Roman numerals I thru VIII. Other notations that may be used are MD for master die, MH for modified hub, Pr for proof coin, (3) for tripled die, and (4) for quadrupled die. EXAMPLE: 1963D 1? 1-O-VII tells us that the coin is a One Cent piece dated 1963, struck in Denver, die #1, the doubling is on the obverse, and is a class VII variety
