History of the Uruguayan Peso: The peso was introduced in 1975, replacing the old pesos at a rate of 1 new peso to 1000 old pesos. In 1993, it was revalued again, with 1 new peso replacing 1000 old pesos. Interesting Facts: Due to currency instability, Uruguayans often had to revalue their peso. The local currency was converted to the US dollar, and prices were quoted in US dollars. This led to the appreciation of the Uruguayan peso.
