The 91 O has lots of examples in circulated condition below AU. The coin is rare in MS 65 condition. The mint released some bags in 1962 of the 91 O as a result the coin can be easily found in MS 61 through MS 64. There are lots of these MS examples that have been slabbed. There are not many examples of this coin available in AU as there are low population counts in AU condition by NGC and PCGS. If a nice slabbed AU55 goes up for auction, you are fighting with other collectors trying to get the coin at the lower price. If you step up to MS 63 it will cost more, but there are more examples available.
