The United States Mint officially stopped producing silver dollars in 1806. It was learned that large quantities of the silver dollars were being sent to Asia, mainly China, because of the silver content. From 1836 to 1839 the Gobrecht dollar was minted in small numbers to see if people would again like using a silver dollar. The new Mint Director Robert M Patterson, hired Christian Gobrecht to design the coin. People complained that Gobrecht’s name was too prominent on the coin, so the coin was modified to make it less visible.
