There are two significant varieties for the 1860 Eagle, the 'rounded bun' and 'bulging bun'. Liberty's hair is bound by strings of beads. There are three folds, or buns. The middle bun is either rounded or bulging, hence the variety name. The 'bulging bun' variety was last minted in 1847. It is curious that it would be revived thirteen years later, perhaps a long-shelved hub was brought into service by the Philadelphia mint.
