This 1 Euro piece from 2005 is a standout item from Monaco's Fantasy euro currency set. On the obverse, the intricately detailed Palace of the Prince of Monaco is prominently showcased, surrounded by the multilingual descriptors "PRUEBA TRIAL ESSAI PROBE" and the caption "PRINCIPAUTÉ DE MONACO". The reverse displays a seated woman facing right, elegantly adorned with stars above and below her, with intersecting lines across the figure. The definitive mark "1 SPECIMEN" rounds off the reverse design. This coin is an essential pick for collectors interested in fantasy coinage and the numismatic heritage of Monaco. It's interesting to note that since the Euro was incorporated, no European country has issued a trial coin. All these fantasy euro coins are made in private workshops or shops. These euro coins don't have numismatic value.
