The Series we have called “Face Value Exchange Series“ is made up of the issue of one coin each year (in some exceptional years two were issued) from 1994 to the present. We grouped these coins into a single series since they all have the characteristic that, despite being made of silver, they could be obtained at the Bank of Spain at the face value of the coin and all these coins have the same dimensional and composition characteristics (Silver (.925) • 27 g • ⌀ 40 mm). It started with the Peseta System in 1994, with a face value of 2000 Pesetas (approximately 12 Euros) and continued with the Euro System with face values ​​of 12 Euro (2002-2010), 20 Euro (2010-2011), 30 Euro (2012-2021) and 40 Euro (2022-date).The year 2012 marks the 10th anniversary of the launch of the Euro. Euro coins and banknotes were released into circulation in 12 European countries on January 1, 2002.This is the first coin in the world to have a QUADRUPLE LATENT IMAGE. The reverse depicts four circles arranged in the shape of a cross. Depending on the angle at which they are viewed, the circles will reveal eitther a crowned M, the Roman numeral X, the Euro symbol, or a star.
