Awesome historical coin. I would want anything before the euro. I would need to learn a little more history of this coin before I could appreciate it as much as I need to before bidding. Neat auction though. I'll check back later!
Here is a little history of the paseta from wikipedia :
The peseta was introduced in 1869 after Spain joined the Latin Monetary Union in 1868. The Spanish Law of June 26, 1864 decreed that in preparation for joining the Latin Monetary Union (set up in 1865), the peseta became a subdivision of the peso with 1 peso duro = 5 pesetas. The peseta replaced the escudo at a rate of 5 pesetas = 1 peso duro = 2 escudos.
The peseta was equal to 4.5 grams of silver, or 0.290322 grams of gold, the standard used by all the currencies of the Latin Monetary Union. From 1873, only the gold standard applied.
The political turbulence of the early twentieth century (especially during the years after the World War I) caused the monetary union to break up, although it was not until 1927 that it officially ended.
In 1959, Spain became part of the Bretton Woods System, pegging the peseta at a value of 60 pesetas = 1 U.S. dollar. In 1967, the peseta followed the devaluation of the British pound, maintaining the exchange rate of 168 pesetas = 1 pound and establishing a new rate of 70 pesetas = 1 U.S. dollar.
The peseta was replaced by the euro in 2002, following the establishment of the euro in 1999. The exchange rate was 1 euro = 166.386 pesetas.
Thanks for taking an interest in the coin! Have a wonderful evening :)
