1922 Eagle Dollar

This coin is known as the "Peace Dollar" and contains .77 ounces of pure silver.  It was minted from 1921-1928 and again from 1934-1935.  Yours, of course, was minted in 1922.  The design, by Antonio de Francisci, features Lady Liberty on the face and a bald eagle on the reverse.  Yours doesn't appear to have a mint mark which means it was minted in Philadelphia.

It has a face value of $1.  Don't use it for that.  Melt value of this coin at today's silver prices is $16.07.  Don't use it for that either.  The collector market values this coin in poor condition around $28 and a 'mint' version at about $500.  It's difficult to judge from your photos but yours looks to be in fair condition and is probably worth $30-40.
