One of the deniers of Louis was indeed very interesting, as it is probably the best-preserved specimen that I have seen for the type: Pic from Lanz. Specs are: AR18x20mm, 0.8g billon denier tournois, of very good title for the time, minted at Glarentza cca. 1314-1315 or July 1316, Malloy 29, Schlumbereger XII, 23. Louis was Prince of Achaea and titular King of Thessalonica during an uncertain period of conflict between the Angevins and the Catalan Company in Greece. He ruled by jus uxoris and was recognized as prince between 1313 and 1315 and then again after defeating Ferdinand de Majorca at Manolada in July 1316. Coins were minted in his name possibly between 1314 and 1315 or in July 1316. There is only one series of tournois recorded for Louis and it only has one small variation (Malloy 29-30, p.365) which makes his coins very rare. His rule as husband of Mathilde/Maude/Mahaut de Hainaut in Morea was supposed to tie the Principality to an alliance between the Burgundians and Angevins against Catalan encroachment. Alas, Louis died childless and the Burgundian investment in this joint venture was minimized. His victory at Manolada though secured the continuation of Angevin overlordship over Frankish Morea. Louis was just 19 when he died.
