Legend of a Coin
is that which is written round the face of a coin. Thus, on a shilling, the legend is round the head of the reigning sovereign; as, VICTORIA DEI GRATIA BRITT: REGINA F: D: (or BRITANNIAR: REG: F: D:). The words ONE SHILLING on the other side of the coin, written across it, we denominate the inscription.
