We've had this discussion before where RIC has listed a coin as rare, but, in fact, it either no longer is considered rare or it was never truly rare in the first place. I have a problem with seller's using the RIC rarity in order to sell. I must admit I annotate coins in my catalog with the RIC rarity, but this is for my own benefit. I suppose that is the reason I asked the question in the first place: What do you regard as rare? Your answer at least gives a reasoning other than quoting RIC.
So, if I understand correctly, the Vetranio coins listed as rare on your web page are 1/20 as frequent as his most common types?
