All legitimate pontiffs in the 250-year period from Gregory III to Benedict VII issued coins, with the exceptions of Stephen II (who reigned for only two or three days), Boniface VI, Leo V, Lando, Leo VI, and Stephen IX. Coins are known also for the Antipope Christopher, but these are probably forgeries. After the death of Benedict VII in 983, no further issues were undertaken. However, some authors list several later tenth, eleventh, and twelfth century popes as also having issued coins, but these attributions are due mostly to faulty research. The so-called issues of Pope Paschal II are later counterfeits. From the last two decades of the twelfth and all the thirteenth and fourteenth centuries, the Roman Senate issued coins under its own name, without reference to the Pope.
