Mite

Easton's Bible Dictionary (1897)

Contraction of minute, from the Latin minutum, the translation of the Greek word lepton, the very smallest bronze of copper coin (Luke 12:59; 21:2). Two mites made one quadrans, i.e., the fourth part of a Roman as, which was in value nearly a halfpenny. (See FARTHING.)

Smith's Bible Dictionary (1863)

a coin current in Palestine in the time of our Lord. (Mark 12:41-44; Luke 21:1-4) It seems in Palestine to have been the smallest piece of money (worth about one-fifth of a cent), being the half of the farthing, which was a coin of very low value. From St. Mark’s explanation, “two mites, which make a farthing,” ver. 42, it may perhaps be inferred that the farthing was the commoner coin.
