Some old coins are worth way more than their face value — especially if they have a rare feature. 1855 San Francisco Coin recently sold for $2.1 million at auction, and it all comes down to the year, mint mark, and a special ‘proof’ finish.
The Big Deal: A Rare 1855 San Francisco Coin
The coin in question was made in 1855 during the California Gold Rush. It was struck at the San Francisco Mint, and you can tell because it has a small “S” under the date on the front (obverse) side.
Back then, this coin was worth $3, but today it’s worth millions because of how rare it is.
Why It’s So Valuable
This isn’t just any $3 coin — it’s a proof coin. Proof coins are made using a special process. They’re usually struck first and made with extra care for collectors or records. They have a shiny, mirror-like surface and are very high quality.
Experts say this 1855-S coin is one-of-a-kind in its condition and quality. It had been in the hands of a California family for many years before going to auction.
It’s made of 90% gold and 10% copper and weighs just over 5 grams. It’s super rare — which is why it sold for $2.1 million in 2023.
