Because the size of the coin and the design elements were so similar to those on the Quarter Dollar, these coins caused a lot of confusion with the general public (similar to the situation that occurred over 100 years later with the Susan B. Anthony Dollar).
For this reason, Twenty Cent Pieces were struck for circulation only in 1875 and 1876. In 1877 and 1878, they were available only as Proofs.
