From Wikipedia, the free encyclopedia
The Venetian grosso (plural grossi) is a silver coin first introduced in Venice in 1193 under doge Enrico Dandolo. It originally weighed 2.18 grams, was composed of 98.5% pure silver, and was valued at 26 denarii. Its name is from the same root as groschen and the English groat, all deriving ultimately from the denaro grosso ("large penny").
Its value was allowed to float relative to other Venetian coins until it was pegged to 4 soldini in 1332, incidentally the year the soldino was introduced.
In 1332, 1 grosso was the equivalent of 4 soldini, or 48 denarii.
