Sicily. Carlo I d'Angio (1266-1282) gold 10 Tari ND AU53 NGC, Messina mint, 7.0g, Fr-653a var, MIR-145/1 var. A very rare multiple Tari issue of Sicily, moderately toned and struck on an oblong flan with the central motifs of the module complete. The weight of a Tari was approximately 0.7g at the time of the minting of this piece, although it is unlikely it was intended to be a specific denomination. Rather, the wide range of weights among extant multiple Tari in combination with the ingot-like quality of the planchets clearly suggest that gold traded strictly by weight on the island, the stamping of coins likely a guarantee of gold purity alone rather than any particular value.
