Here we are offering the Proof 1981 S Susan B Anthony Dollar Coin.

This proof coin was taken from a 1981 proof set.  

This is the Type I coin.  

The Susan B. Anthony dollar coin has all the hallmarks of becoming a highly sought-after collectible. With a short run and high numbers minted, Susan B. Anthony coins still show up in pocket change these days

The entire collection of Susan B. Anthony dollars consists of just 11 coins, minted for 3 short years from 1979 through 1981, then again in 1999 because of high demand created by transit and postal vending machines.

The 1979 year coins were the largest production year for S.B.A.'s.  Since, they weren't very well accepted, the 1980 run was smaller and the 1981 run was never put into circulation.  Instead, they were sold by the U.S. Mint in sets for coin collectors.  Because of their lack of popularity, many sets from 1981 were broken up and ended up in circulation after all.
