Ursula Thaler
The name given to a silver Thaler struck at Cologne in 1516, which has on the obverse the figures of three Magi with their names, and on the reverse a vessel carrying St. Ursula and her companions on the river Rhine to Cologne, where she is supposed to have suffered martyrdom. There exist double and triple Thaler of the same type. See Madai (No. 2188).
