In San Francisco, 1937 was a big year.

To toast the milestone, the Mint hosted a rare behind-the-scenes tour of the facility ("This is what $1 million in quarters looks like," tweeted Haighteration), as well as the release of (get ready, coin fans) a pair of 2012 American Eagle silver proof coins.
Though the Mint's production has slowed in recent years, its historical importance is undeniable in San Francisco. (Our city was built on gold and silver rushes, people.)
"With the California Gold Rush underway in 1849, the United States Mint was overwhelmed with the task of turning all that gold into coins," wrote the Mint on its website. "Transporting it all to Philadelphia for coining was both time-consuming and hazardous. So in 1850, President Millard Fillmore recommended that a branch of the United States Mint be established in California. Congress approved the plan in 1852, and the San Francisco Mint was born."
The first Mint produced $4,084,207 worth of gold in its first month alone. The powerhouse soon outgrew its britches and, in 1874, moved into its new space on Fifth and Mission Streets - the famous Granite Lady.
Built to resemble an ancient Greek temple, the Granite Lady was one of the sole buildings in San Francisco to survive the 1906 earthquake and fire, becoming the only financial institution capable of operating immediately after the disaster. Within days, the Mint was the treasury for disaster relief funds.
Finally, in 1937, the Mint again outgrew its home and moved into a larger, more modern space: its current home at 155 Hermann Street.
