The “1878 Morgan silver dollar 7 tail feathers” designation refers to a specific variety of the initial year of Morgan dollar production. These coins are distinguished by the depiction of seven tail feathers on the eagle featured on the reverse (back) of the coin. This contrasts with later versions which display eight tail feathers. A detailed examination of the reverse is necessary to identify this variety.
The historical significance stems from its being one of the first coins minted under the Bland-Allison Act of 1878, which mandated the purchase of large quantities of silver for coinage. The initial design was quickly modified, leading to the seven-feather variety being produced for a limited time and therefore sought after by collectors. Its importance lies in its role as an early example of the Morgan dollar and a tangible artifact from a period of significant monetary policy change. The relative scarcity compared to other Morgan dollars contributes to its collector interest.
