The 1900-O Morgan is a common coin that is readily available in circulated condition and even up through grades of MS65. The date becomes a little scarcer in the MS66 range and in the MS67 levels it is somewhat scarce, though none are known to grade higher. PLs are scarce, especially in the Gem range. DMPLs are rare in all grades.
