Hi - I am curious where you got the dates for the 25 and 50 Pesetas because the 25 and 50 Pesetas issued in 1982 are the same material and weight as those issued under Juan Carlos since 1975. According to the Bank of Spain only those coins having the same weight, diameter and metal content as the coins circulating before adoption of the Euro are exchangable. From what I see in Krause the holed Nickel-Bronze 25 Pesetas was not issued until 1990 and the notched 20.3mm 50 Pesetas coin was also not issued until 1990. Has anybody had success redeeming the older, larger coins?
"It should be noted that the obverse and reverse designs shown here are purely illustrative, since they generally changed every year. The distinguishing features of the coins that were in circulation are the alloy, or colour, and the diameter.
These coins, together with the 2,000 pesetas coins, are the only ones that can be exchanged at the Banco de España indefinitely." Source:
