Coin of 500 réis from 1876, in silver, of King D. Luís I, also known as the five tostões silver coin of 1876, minted during the reign of D. Luís I in Portugal (World Coins – Portugal, KM#509). The date 1876 is the second rarest in the 500 réis series of this reign, which gives it special numismatic interest. King D.

Nicknamed “The Popular,” he was the thirty-third King of Portugal; he was born in 1838 and reigned from 1861 until his death in 1889. His wife was D. Maria Pia of Savoy
