What you're looking at here is proof that price is a function of both supply and demand. 1921, being the only high relief Peace dollar, is desired by both typeset collectors and series collectors, as well as those who want "key" US coinage. All the other Peace dollars, by and large, have only series collector interest. With that said, a 1928 is pricier in-grade than a 1921, as is a 1927-S in Mint State, and 1934-S is pretty much prohibitive in Mint State - they must have circulated heavily.
The one that makes me
is 1927-P. The second-lowest mintage in the series, and they're downright cheap (relatively speaking) until MS65. Most of the issue must have survived, leading to a theory that west coast coins circulated more.
