the estimated value of an 1800 Dollar in Mint State (MS) is between $30,000  and $310,000 in the current market;

This was the final year of high production for silver dollar coins before coinage was suspended in 1804 for more than 30 years. Both the dropping mintages and the ultimate suspension were due to the large exportation of American silver dollars overseas for their bullion value, effectively making them obsolete in domestic commerce. This void was filled with the resumption of half dollar production in 1801, which grew annually thereafter. The date 1800 is fairly common in circulated grades, though Mint State pieces are in very short supply. There are 16 die marriages known for dollars dated 1800, and a notable feature is that the mixing and matching of obverse and reverse dies so prevalent for earlier dates was reduced in 1800. Thus, the ratio of dies made to die marriage is much closer than in earlier years. This tends to suggest also that carryover of older dies into this year was likely reduced, with most of 1800's production being dollars bearing that date. A common yet popular variety is the so-called AMERICAI issue. One reverse die suffered a small break following the second A of AMERICA, creating the illusion of a crude letter I. This die was paired with two obverses (BB-191 and BB-192), and neither marriage is rare. In fact, the only rare marriages for 1800 are BB-182, BB-183 and BB-185.
