After the death (24 December 1221) of Arnold von Matsch, Heinrich von Rialt was proposed as Heinrich (III) in a double election
by the cathedral chapter together with Albert von Güttingen as Bishop of Chur. However, he (likewise Albert von Güttingen)
died in 1223 before the Pope could decide between the two pretenders. It therefore is more likely that coins in the name of
(H)ENRICVS from the bishopric of Chur were issued by Heinrich III of Montfort (1251-1271) - or Heinrich II (1180/84-1193/94).
