The Abbey-Principality has recently acquired an example of the insignia of the Order of the Crown of Thorns from the early twentieth-century. This is the insignia of a chevalier (knight). It was manufactured by the firm of Schubauer es Miticzky of Budapest, Hungary, and is presented in a specially moulded case. There are few known members of the Order in Hungary; the most prominent was Archbishop Count Victor J. Alexander de Kubinyi (1873-1966), who served in the Apostolic Episcopal Church.

The design is in accordance with other known examples of this period, and the high quality of the gilding and enamelling is notable.
