A notable example, according to Executive Digest, is the case of 1 cent coins, a denomination that is often devalued due to its low nominal value. However, some of these coins have become true gems in the world of numismatics.

According to Postal news, one example is the coin designed by German architect Rolf Lederbogen, whose scarcity caused some copies to be auctioned for exorbitant values, up to 50 thousand euros in some cases.

Another example occurred in Italy, where a minting error on a 1 cent coin generated great interest among collectors. This coin, with a smooth edge and specific physical characteristics, presented an incorrect image: instead of the Castel del Monte in Puglia, it displayed the image of the Mole Antonelliana in Turin, which should belong to the 2 cent coin.

This mistake led to their rapid withdrawal from circulation, but it is estimated that around a hundred of these coins may still be in circulation, reaching values ​​of up to 6,000 euros in specialised auctions.

For enthusiasts looking to expand their collections in search of these rarities, it is essential to consult an expert to verify the authenticity and value of the coins.
