In 1962, an individual redeeming a silver certificate received a rare Morgan silver dollar in return, touching off a frenzy of people redeeming silver certificates for silver dollars. The US Treasury later learned that they had about 2.8 million uncirculated nineteenth century Morgan silver dollars. The General Services Administration (GSA) was tasked with selling these collectibles to collectors, who paid premiums to get the coins, which still fetch high prices today. In which city's mint were these rare coins struck? This city's mint operated 1870-85 and from 1889-93 in a state capital, and is the only mint with a two-letter mint mark.
