San Francisco, to a Coin Collector 8

In 2010, San Francisco had a population of 805,000, and is well known culturally and commercially. However, when it was founded by Spanish colonists in 1776, San Francisco (Saint Francis in Spanish) was just a small peninsula. What would bring people to San Francisco?


In 1848, San Francisco had a population of 1,000. In January, 1848, James Marshall discovered gold at Sutter’s Mill, about 40 miles from present day Sacramento. News of this would bring over 300,000 people across the country and the sea to make their wealth. This would bring people to San Francisco and by 1849, it blossomed to 25,000 inhabitants.

San Francisco was growing so much that the US mint was determined to build a branch there. In 1854, the first San1854-S Twenty Dollar Gold Reverse Francisco mint opened in a small brick building. The first year, they minted over $4,000,000 in Gold Coins and the following year, they started minting Silver Coins as well.

Gold was in demand at the eastern banks but with no intercontinental railroad, and the difficulty of traveling across the country because of robbers and Indians, the only way to get the gold there was by sea. There was no Panama Canal back then. So, you had to travel months around South America. Although there was no canal, they would take a boat from San Francisco to the isthmus of Panama, travel across, and take another boat to the Eastern US coast. The most popular boat to take San Francisco gold was the USS Central America. Besides passengers, it had a cargo of over $2,000,000 of gold coins and bars. In September, 1857, the ship encountered a hurricane off the coast of North Carolina. Some of the passengers were rescued by other ships, but all the gold went down with the ship. With the Central America not reaching New York City, the country went through a financial crisis until the Civil War began.

In 1874, the mint was moved to a new building made of stone that looked like a Greek temple (known as the Old Mint and “The Granite Lady”), and minted coins up to the 1906 earthquake. The building itself survived that and the fire afterwards, but the gas works were partially destroyed, delaying minting coins for a short tim1968-S Lincoln Cente. When they reopened, they expanded beyond silver and gold coins by minting the Indian Cent in 1908 and the Liberty Nickel in 1912. They used this building until 1937 when they built the current building.

Operations continued until 1955 minting the Lincoln Cent and Roosevelt Dime. Production wouldn’t resume there
until the 1965 Mint Set. Before then, the ‘S’ mint mark appeared on the reverse of coins. The 1965 – 1967 SMS coins did not have a mint mark. In 1968, San Francisco would start producing proof sets, which previously was done in Philadelphia. They did produce circulated Lincoln Cents from 1968-1974 and Jefferson Nickels from 1968-1970. The mint mark would appear on the obverse starting in 1968.

While in San Francisco, visit the US Mint2006 San Francisco Mint Coin

San Francisco has had a US mint branch longer than any other city, with the exception of Philadelphia. They still produce the US Proof Sets as well as commemoratives. The Old Mint building has been designated a National Landmark in 1961 and a California Historical Landmark in 1974. The Old Mint was sold to the city in 2003 to become the San Francisco Museum at the Mint. The Old Mint was honored on a silver commemorative dollar and gold $5 piece in 2006, the first coin to be displayed on a coin.

Have you ever visited the San Francisco mint or museum? I’d like to hear about it.

    Hey Kevin,

    I liked your post. I did not know that people moved to San Francisco because of Gold. If I knew, maybe I tried to immigrate there in 1848 too! lol )
    Also it’s great to know about US mint in San Francisco. Unfortunately I’ve had not chance to be there yet but I would be happy to visit us, San Francisco and mint and museum over there one day.
    Looking forward to read your next posts )

      Thanks Sandra! You should visit the US. There is a lot to see here. I’ve never been to San Francisco but hope to get there someday and visit the mint.

    Interesting article on San Francisco. I have heard that it is a coin collectors paradise but I never really knew why. I didn’t actually know that the mint is located in San Fran. So the mint branch is the 2nd oldest behind only Philadelphia? I went to the philadelphia mint as a child but I was not aware that San Fran also has an important branch. I will be sure to check it out on my next trip to California!

      It’s not the second oldest mint in the country, but it has been open longer than any other mint, except Philadelphia which has been running since 1792. I haven’t made it to any of the mints except for the Bureau of Printing and Engraving in Washington, DC. I always say I am going to the Philadelphia Mint since that one is closest to me, but haven’t made it there yet.

    Kevin – Great picture of the Golden Gate bridge. I liked your content. I saw a documentary on the shipwreck of the USS Central America. What a story. Didn’t they just recently discover the wreckage. I have been to the mint in Kansas City and will certainly check out the one in San Francisco if I ever get out there.

      Yes, Thomas Thompson discovered the wreckage off of South Carolina. He found millions of dollars of gold coins and bars but was sued by groups that had insured the boat for over a century. I believe another expedition went out a couple of years ago and I think they were promised a percentage of the findings.
