Italian 1957 Treaty Commemorative

In 1957, Italy became the first nation to issue a silver commemorative coin specifically for the Treaty of Rome, symbolizing the birth of the European Economic Community.

That coin, a 500 lire piece, was struck from 0.835 fine silver and featured a design by artist Pietro Giampaoli, showing two hands clasped in unity over a map of Europe. While the obverse bore the Italian Republic's emblem, the reverse highlighted the treaty's focus on economic cooperation, a nod to postwar recovery efforts. Mintage figures are murky; official records from the Rome Mint might have been incomplete, as was common in that era.

Some enthusiasts claim it predicted the euro, but that's just wishful thinking—it's simply a product of its time.
