The Susan B. Anthony dollar was first introduced in 1979, as the US government sought to replace the $1 bill with a coin. The coin was named after Susan B. Anthony, a prominent American suffragist who fought for women’s rights and was a key figure in the women’s suffrage movement. Despite its historical significance, the Susan B. Anthony dollar was not very popular with the public and was eventually replaced by the Sacagawea dollar in 2000.

In terms of its value, the Susan B. Anthony dollar is not particularly rare or valuable. In fact, the coin was produced in large quantities and is still relatively easy to find in circulation or through coin dealers. The coin itself is made of copper-nickel and is roughly the same size and weight as a quarter, which makes it easy to confuse with other coins.
As of 2021, the value of a Susan B. Anthony dollar is largely determined by its condition and rarity. A typical uncirculated coin in good condition may be worth around $1.50 to $3.00, while a proof coin or one in excellent condition could be worth significantly more. In addition, there are a number of rare or error versions of the coin that can be quite valuable to collectors.
Some of the most valuable Susan B. Anthony dollars include those that were minted in smaller quantities or with special markings or errors. For example, some of the 1979 coins were struck with a “filled S” error, in which the mintmark on the coin was filled in and appeared as a solid blob. These coins can be worth up to $500 in uncirculated condition. Similarly, some of the 1981 coins were struck with an error in which the “P” mintmark was left off, which can increase their value significantly.
Another factor that can affect the value of a Susan B. Anthony dollar is its rarity. While the coin was produced in large quantities, some years or mintmarks are rarer than others. For example, the 1981-S proof coin was only produced in limited quantities and is relatively rare, with only a few thousand known to exist. As a result, this coin can be worth upwards of $50 or more in uncirculated condition.
Overall, the value of a Susan B. Anthony dollar depends on a number of factors, including its condition, rarity, and any special markings or errors. While the coin is not particularly rare or valuable in general, there are a number of versions that can be worth significant amounts to collectors. If you have a Susan B. Anthony dollar and are interested in selling it or determining its value, it may be a good idea to consult with a professional coin dealer or appraiser who can help you assess its worth.
