Notes:
The 1904 Silver Dollar is somewhat scarce in Uncirculated condition, despite a seemingly high mintage.  Prooflike and Deep Mirror Prooflike examples are extremely rare, as indicated by the dearth of listings below.  The finest Uncirculated examples graded by PCGS are 9 MS-66's, 5 MS-64 Prooflikes, and a single MS-65 Deep Mirror Prooflike.

Like the 1903 Proofs, this date is seen most often in PR-63, in which grade this date enjoys one of the highest populations in the series.  The finest Proofs graded by PCGS are only 4 PR-67s.  No Cameo or Deep Cameo Proof 1904 Silver Dollars have been graded by PCGS.
