This 500 Lira type was the first bimetallic coin minted in the world.
It´s also the world’s first coin to be issued with Braille on the reverse. The Braille system is a method that is widely used by blind people to read and write, and was the first digital form of writing.
Braille was devised in 1825 by Louis Braille, a blind Frenchman.

The Quirinal Hill (Latin: Collis Quirinalis; Italian: Quirinale) is one of the Seven Hills of Rome, at the north-east of the city center. It is the location of the official residence of the Italian head of state, who resides in the Quirinal Palace; by metonymy "the Quirinal" has come to stand for the Italian president. The Quirinal Palace has an extension of 1.2 million square feet. It was originally part of a group of hills that included Collis Latiaris, Mucialis (or Sanqualis), Salutaris. These are now lost due to building in the 16th century and later. In the Middle Ages, the Torre delle Milizie and the convent of St. Peter and Domenic were built, and above Constantine's building was erected the Palazzo Rospigliosi; the two famous colossal marble statues of the "Horse Tamers", generally identified as the Dioscuri with horses, which now are in the Piazza Quirinale, were originally in this Palazzo. The obelisk from the Mausoleum of Augustus was erected 1781 – 1786.
