Pfennig - Leopold III or Leopold IV

The attribution to either Leopold III or Leopold IV reflects a genuine scholarly impasse — the iconographic and stylistic evidence places these bracteate-style pfennigs squarely across a dynastic transition that Austrian numismatists have debated for decades without resolution. Leopold III, later canonized in 1485, was the margrave who founded Klosterneuburg and shifted the Babenberg seat to that location; his son Leopold IV held the march only briefly before his death in 1141. The minting authority between them was never cleanly delineated in surviving documentary sources.
