The Decree of 19 October 1868, which created the peseta, set for the 5 pesetas silver coin an exact weight of 25 g, an exact fineness of 900 thousandths and a diameter of 37 mm. That equals 22.5 g of pure silver.
Melt value right now: … per piece (metal only).
Silver of 900 and 835 thousandths
The same decree set a lower fineness of 835 thousandths for the 2-peseta and 1-peseta pieces struck on account of the State:

What about my Alfonso XII or Alfonso XIII duro?
Here we only publish what the 1868 decree says. We have not checked in an official text which rule governed each later minting, so we do not claim it. If your coin is from another reign, weigh it and use the calculator with its weight and the fineness marked on the piece.
Melt value is only a reference floor: rare dates or well-preserved pieces can be worth more to a collector.
