You know that Peace Dollars have Liberty's head on them, but did you know Longacre designed the Indian Head cent with the same Liberty Head? The difference between the Indian Head Cent and the Peace Dollar, besides the size, is on the cent Liberty is wearing an Indian headdress and on the Peace Dollar she's wearing a crown.
Did you know on all Indian Head Cents from 1859 until mid-1886 the last feather of the headdress points between I and C of America and on all Indian Head Cents from mid-1886 through 1909 it points between C and A? This means both varieties were struck in 1886, thus there is an 1886 variety 1 and an 1886 variety 2. Variety 2 is scarcer and is worth slightly more.
Hope you enjoyed this bit of trivia.
