Coinage used in The Middle Ages (in The Middle East and Sicily), The Tari was minted and in circulation from the 11th to the 13th Centuries. Weighting 1.30 grams, a common issue with The Tari was it's continued “lack” of weight during minting. Some weighed less (other more). This seriously under valued The Tari. The coins did have good engraving quality. They did not have “international” appeal as a result of this.
