In the world of coin collecting, certain coins are more than just pieces of metal—they are legends. One such coin is the 1870-S Seated Liberty Dollar. This rare dollar is not only valuable, but it also has a mysterious past that makes it one of the most talked-about coins in American history. What makes this coin special is that it was never supposed to exist, yet a few were somehow made. Today, it’s considered one of the greatest treasures in U.S. coinage. Let’s explore the story behind this legendary rarity and why collectors are still fascinated by it more than 150 years later.
Coin Name: 1870-S Seated Liberty Dollar
The Seated Liberty Dollar was part of the U.S. Mint’s silver dollar series, first introduced in the 1840s. It shows Lady Liberty seated on a rock, holding a shield and a staff, symbolizing strength and freedom. The reverse features a classic bald eagle design. Now let’s talk about the 1870-S version—the “S” stands for the San Francisco Mint, one of the main mints at the time. What makes this coin incredibly rare is that no official record exists of it being made at the San Francisco Mint in 1870. According to mint records, only Seated Liberty Dollars from Philadelphia (no mint mark) were issued that year.
However, a few 1870-S Seated Liberty Dollars were discovered over time. Experts believe that only 9 known examples exist today. It’s believed these coins were made in very small numbers—possibly just for display purposes during the opening of a new mint building in San Francisco or as presentation pieces for dignitaries. The mystery of its creation, combined with the tiny number known, makes this coin one of the rarest silver dollars ever struck in the United States.
Why the 1870-S Liberty Dollar Is So Rare and Valuable
There are several reasons why the 1870-S Seated Liberty Dollar is so legendary:
- It wasn’t officially recorded – The U.S. Mint kept no record of its production.
- Extremely low mintage – Fewer than 10 are known today.
- Historical mystery – No one knows exactly why or how they were made.
- High collector demand – It’s a “holy grail” for serious numismatists.
One of these coins sold at auction for over $1 million, and the value could be much higher depending on its condition and history. Because it is so rare, the coin is rarely seen for sale—and when it is, collectors go wild.
