The 2004 San Marino 2 euro commemorative coin honours the life and scholarly contributions of the Italian numismatist and epigrapher Bartolomeo Borghesi. The national side of the coin features a portrait of Borghesi, whose extensive research into Roman coins and inscriptions significantly advanced the field of historical study. His work remains deeply connected to the identity of San Marino, where he resided for many years and conducted much of his academic output. Surrounding the portrait are the name of the scholar and the inscription 'San Marino', reflecting the nation's respect for his intellectual legacy and his role in preserving European history. This issue was released in 2004 as a standard circulation coin.
