2 Euros - San Marino Grand Prix

San Marino's 2005 commemorative program coincided with the country's long-running sponsorship presence in Formula One, where the "San Marino Grand Prix" had been held annually at Imola since 1981 — despite no part of the circuit lying within San Marino's actual 61 square kilometers. The race borrowed the name largely for marketing reasons tied to regional tourism, a geographic fiction that the FIA tolerated for decades before the event was dropped from the calendar after 2006.
