(US) An eighth of a dollar. Note that there is no coin minted worth 12.5 cents. (When this term first came into use, the Spanish 8 reales coin was widely used as a dollar equivalent, and thus the 1 real coin was equivalent to 12.5 cents.)
(historical, US) In the southern and southwestern states, a small silver coin (such as the real) formerly current; commonly, one worth about 12½ cents; also, the sum of 12½ cents.
