Wow, 1921 Peace dollars are "frothy" in auctions!

I've been seeing it all across the board for this date, especially in MS-63 and up:
This is just the other day:

Got this one in my thread below for just under $750 about 5 years ago, maybe I should sell? Actually not, I like this coin too much.

@ElmerFusterpuck .... I really like that MS64 you have.... nice detail. Cheers, RickO
21 peace dollars accross all grades have been nuclear at auction. I regret selling all the ones i did in years past and wish i would have picked up more.
I wonder if it's just a bubble driven by centennial year hype, or a lasting upward trend?
I can’t really imagine why it would be the latter.

I noticed it when the price guides jumped way up a few months ago.



I currently have (2) in 63 and an ogh 64. I like the look of all three.
I think the centennial year is a factor, due to the publicity generated by the forthcoming 2021 Morgan and Peace dollars. Some collectors will want matching 1921's.

Although I don't have much data to support this feeling, it seems like prices are reasonably strong at the moment for nice examples of "moderately" priced (e.g. < $ 1000) coins across a range of series.
