The escudo was either of two distinct Spanish currency denominations.
Between 1809 and 1849, coins denominated as 80, 160 and 320 reales (de vellon) were issued, equivalent, in gold content and value, to the 2, 4 and 8 escudo coins.
Most were minted in Madrid, marked with a superscripted M or in Seville bearing an S below and left of the Royal Coat of Arms.
The mintmaster's initials appeared on the opposite side.
It was itself replaced by the peseta, at a rate of 2+1⁄2 pesetas = 1 escudo, when Spain joined the Latin Monetary Union.
