This is a good question, and it is difficult to answer in an easily explainable way. All 1921 Peace dollars were struck in high relief, while most 1922 coins were struck in low relief, and practically all 1922 coins you will see today are low relief. There was an earlier thread about this.
Let me lend a hand here . On the 22, there's two reverses . First there's the B1 : B1 Reverse Design Reverse B1: Note two mountain peaks, 3 rays below ONE, 6 rays below Eagle's tail, and detached olive branch. Then there's the B2 : B2 Reverse Design Reverse B2: 3 mountain peaks and attached olive branch. Nothing special with the 23 to look for ..
Thank you. I was at a loss to provide specifics and pictures for this. But what about the "high relief versus low relief" question?
But those are proofs. Are all the 1922 high relief Peace dollars matte proofs? (I forgot there was even such a thing as a proof Peace dollar. Wow- rare birds!) If that is the case, then we can easily answer @Shanesbird1027's question, since her coin is obviously not a proof. (Not that I expected it to be anything but a low relief business strike like practically all the 1922 Peace dollars out there, anyway.)
I was thinking there were some high relief 1922 business strikes made but they were all destroyed, There were also some 35,000 MEDIUM relief pieces made. Frankly they are pretty much impossible for me to tell from the high reliefs. Best place to look is the spike just right of E in LIBERTY. It come just up to the top of the bottom leg of the E (See the high relief Matte Proof image up above, the Medium relief is exactly the same) Of those 35,000 a single example is known today. If was found in a bunch of "junk" dollars.
@Shanesbird1027 is by now no doubt completely confused. LOL But it's safe to say her coin in the OP is low relief, I would assume.
