Watch List notes:

Ryan, John Carlin, A Handbook of Papal Coins: The Medieval Coinage, 1268-1431- The Early Renaissance Coinage, 1431-1534, Washington, D.C., 1989, 81 pages, softcover, line drawings throughout, a truly wonderful book encompassing a somewhat narrow but critical 275 years of Papal coinage, from the resumption of distinctly Papal coins in the late Mediæval period through the coinage of the Renaissance. Covering the period 1268 to 1534, this book contains not only listings and a typology of these coins, but also copious background information unavailable elsewhere, at least not in English.
