12-euro coins: from 13 to 47 euros in 12 years

The Bank of Spain's 12-euro coins: from discard to silver bonanza

In 2013 they were bought for 13.75 euros. At the start of 2026, the same coin is quoted at 47.50 euros on the secondary market. The 12-euro coin issued by the Banco de España, minted in 925 sterling silver, has gone from being a simple collectible souvenir to becoming a financial asset in its own right. No one had told it this way until now.

The price journey: from 13.75 to 47.50 euros

The first records of this secondary market date back to May 2013, when bids reached 13.75 euros per coin, just 1.75 euros above its face value. Demand was moderate, with lots of 250 to 300 units. By June of the same year, prices had already fallen to 12.05 euros, touching the floor of 12 euros. The coin was worth the same as its printed face.

The turning point came with the silver rally. In October 2024, the asking price (ask) already exceeded 17 euros. A year later, in December 2025, 32.99 euros were being asked. By February 2026 there are those offering lots of 500 coins at 42 euros. And in June 2026, a seller is asking 47.50 euros for the complete collection of the ten different coins issued.

That is, in just over a decade, the value has risen 245% if one takes the highest bid of 2013. And that is without counting the certainty that, come what may, the Banco de España exchanges them for their face value.

The investor's dilemma: silver or face value?

The 12-euro coin contains 16.65 grams of pure silver (0.5353 troy ounces). With the metal price around 1.88 euros/gram in the latest updates, the silver content is already worth about 31.30 euros. But the secondary market pays even more: the premium over intrinsic value reflects scarcity and confidence in the product.

There is a recurring debate among savers: do you prefer to hold pure silver bullion coins (more grams per euro) or these coins with a guaranteed floor? The former give more exposure to the metal; the latter, insurance against losing all your capital. Recent history proves right those who bet on physical silver, but the fall in the value of the euro since 2021 has made even the 12-euro face value seem like a joke. As is repeatedly argued, the loss of value of fiat is really serious. The 12-euro coin, which was born as a simple commemorative means of payment, has become a refuge against monetary inflation.

What to expect?

For now, the trend is upward. Silver has marked nominal all-time highs in 2024 and 2025, and the metal remains an industrial asset with growing demand. However, the market for these coins is small and very liquid only within communities of collectors and investors. Any correction in the price of silver would drag these pieces down with it.

A revealing fact: jewellers are happy because they have 925 silver cheaper than buying 999 and alloying. This indicates that part of the demand comes from the jewellery industry, which melts the coins to obtain the metal. But as long as the price remains above the value of the content, collectors will hold their own.

At the end of 2026, the highest ask recorded is 47.50 euros for the complete collection, but there are those asking 42 euros per single coin in Vizcaya. The range is wide and suggests there is still room for the price to rise if silver maintains its tone. Or not: if the ECB raises rates and strengthens the euro, the refuge could sustancia ilegal. Time will tell if this coin remains a drag or becomes a true silver mine.
