1921 Peace Dollar Error Strike

Thank you very much. I'm new to this forum and actually its my first.

In 1921 the Mint had trouble striking Peace silver dollars.
The relief on the coin was designed to be too high for proper striking.
Hence many were softly struck.
You have one.

The problem was corrected (as much as possible) in 1922.

Very few 21 Peace dollars are exceptionally struck. I'm kinda of an expert on this date due to a lot of research when I got my own. High relief on this coin greatly affected the strike in the center of the coin....,libertys hair by her ear is almost always flat and weak, Eagles breast feathers are normally weak and undefined. Your eagles breast feathers look decently struck, but the hair on the obverse is weak, which is typical. Dave is correct fully struck 21 Peace dollars sell for crazy premiums cause they are extremely scarce. You have a nice coin and a 64 grade is nothing to insult, it's a good $500 or so piece. This is why the mint stopped doing high relief on the Peace dollars cause of these issues....21 was the only year with the high relief the exception 1922 of which there are like a dozen trial strikes which are big $$$$. If you have any other questions about this coin please feel free to PM me.

Many thanks to the many helpful replies to my post. I don't see a way to thank you all individually but I'm on a learning curve today.
