Crosslet 4

Notes:
The Turban Head type was discontinued in 1804 and no more $10 Eagles were struck again until 1838 (with the unique exception of the 1804 Proofs that were struck in 1834 for inclusion in diplomatic presentation sets).  This date is very rare due to a low mintage and the deliberate destruction of many of the coins whenever their bullion value exceeded their face value in the early 1800s.  Circulation strikes came from a single pair of dies and they are distinguished from the Proofs in a variety of ways, but most noticeably by the fact that they have a Crosslet 4.  Taraszka lists a single Proof from the original dies (this coin is now in the Smithsonian Institute).  The extremely rare 1804 Proofs struck in 1834 have Plain 4's (see the illustration above).  

Silver versions of the 1804 Plain 4 Eagle are known (Judd 34).

As of April 2005, PCGS certified 35 examples of the Crosslet 4 variety, eight of which earned a Mint State grade.  The finest of the Mint State examples were 2 MS-63's.

As of April 2005, PCGS had certified three examples of the Plain 4 Proofs, including 2 PR-63's and 1 PR-64.

Die studies show that the 1804 Crosslet 4 Eagles were struck before one of the 1803 varieties!
