I agree that Peace dollars are indeed beautiful coins. I think they don't get much attention because it's so hard to find one with a really good, clear strike and nice luster. But you can't fault the design, especially the reverse. I also find that they're hard to grade because they are often so weakly struck. But I still love 'em and only need two more to complete my set. Guess which ones.
Bingo! I haven't had any trouble finding 1921's, but I'm just not prepared to spend the money for these two yet. Someday...
