What US silver dollars are rare?

Morgan Dollars and peace dollars

Silver dollars were issued from 1794 to 1935 so there's a lot of ground to cover.

Among the rarest are those from 1794 and 1795, with prices in excess of a million dollars for top-quality specimens. See below for information on "1804" dollars.

High-value seated Liberty designs include 1870-S (again, over $1M) and 1873-CC ($100,00+)

Morgans are more common although a few make it to the $20,000 and up range: 1889-CC, 1892-S and 1895 proofs.

Not many Peace dollars command high prices. In XF or lower condition, only the 1934-S issue cracks $1000.

Modern $1 coins are of course not silver - they're copper-nickel or brass.

"1804" dollarsThis date is by far one of the most expensive American coins, with auction sales approaching 8 digits. However, all genuine "1804" dollars were actually minted much later to supply coins for various presentation sets. They're not considered counterfeits because they were made by the US Mint itself! Needless to say, there are millions of actual counterfeits so be VERY wary of anyone trying to sell a supposed "1804" dollar.
