It's a fantastic question that brings up a common point of confusion for collectors. While you're asking about a 1922 Susan B. Anthony dollar, that specific coin doesn't actually exist. The Susan B. Anthony dollar was minted much later, from 1979 to 1981 and again in 1999. What you almost certainly have in your hands is a 1922 Peace Dollar, a truly classic and beautiful piece of American history.
The great news is that the 1922 Peace Dollar is a genuine silver dollar, containing 90% silver. This gives it a solid base value based on its silver content alone, which fluctuates with the market but is often in the $17 to $20 range. This is the absolute minimum your coin would be worth.
However, its true value is revealed when you look closer at its condition and mint mark. The 1922 Peace Dollar is one of the most common coins in the series, so circulated, well-worn examples will typically trade for a value close to their silver melt price.
The key to unlocking higher value lies in the coin's preservation. If your coin is in uncirculated, or "Mint State" (MS), condition, its value climbs significantly. An uncirculated 1922 Peace Dollar can easily be worth $30 to $60. For coins in exceptionally pristine condition, professionally graded at the highest levels, the value can soar into the hundreds or even thousands of dollars. The mint mark, a small letter found on the reverse side ('D' for Denver, 'S' for San Francisco, or no mark for Philadelphia), can also play a role, but for the common 1922 issue, the coin's grade is the most important factor. So, take a close look at your coin; you're holding a genuine silver treasure from the Roaring Twenties.
