As there are only a total of fifteen genuine 1804 Silver Dollars known, it is not too difficult to determine which can be considered to be the finest known. However, to determine the value is much more difficult, especially due to the infrequent public offerings of this issue. A total of eight (roughly half of all known specimens) are currently held by private collectors; the majority being Class I pieces. When sold at public auction it appears that there is no noticeable difference in price between a Class I coin and a Class III coin. Both classes are considered to be genuine Mint products and are sold for large amounts.

As can be expected from a coinage issue which was specifically produced for presentation purposes, a number of 1804 Silver Dollars have survived in remarkable condition. The finest of these is the so-called Watters-Childs specimen, graded by PCGS as PR-68, and is believed to be the coin that was presented to the Sultan of Muscat in 1834. This is the highest numerical grade which has ever been awarded to a 1804 Silver Dollar. The coin last sold in April 1999 for an amazing $4.14 million, a record price for this issue, and also one of the highest prices a United States coin has ever brought at public auction.

The second finest Class I 1804 Silver Dollar is the coin which is part of the King of Siam set, the only complete 1804/1834 presentation set, still in existence (including wooden box) up to this day. It is believed that this set has privately traded for as much as $15 million. Other pieces are graded PR-65, PR-64 and PR-62, while a few impaired specimens also exist. One coin is graded VF-30 and appears to have been a pocket-piece of a wealthy individual.

As previously mentioned, four of the six known Class III 1804 Silver Dollars show artificial wear. The other survivors are also in relatively low condition, having graded PR-63 and PR-60. One coin is graded by PCGS as PR-58 and last sold in April 2009 for $2.3 million. One coin is graded by NGC as PR-55 while the other two are graded EF-40.
