Having only recently bought the 2007 edition of RIC II, I started to convert my RIC numbers from the old 1926 edition to the new one. I was not surprised to find many changes in the rarity ratings, untill I came across a Titus sestertius issued under Vespasian (see: http://www.forumancientcoins.com/gallery/displayimage.php?pos=-83299
). I have another example (same dies) in my very small collection of Titus sestertii. It was RIC 610 C (common) in the old edition. In the new edition it would correspond to RIC 425 which is rated R2 (very rare). I did not expect that. Am I overlooking something?
