In 1997 the International Currency Bureau issued some private Euro patterns, to be honest they were much nicer than the coins that were finally struck by the European Union.
The one on offer is a full crownsized piece struck in brass. On one side you have the famous Italian Leonardo Da Vinci, painter, inventor and all round great thinker. On the other side you have his most famous painting, the Mona Lisa which is now in the Louvre in Paris. These are in Uncirculated condition and are now 20 years old.
