The "Vierzipfliger" type — named by collectors for its distinctive four-cornered flan shape, a product of irregular cutting rather than any intentional design — emerged from the Laufenburg branch of the Habsburgs during a period when the family's Rhine holdings were still being consolidated against competing ecclesiastical and secular claims. The Laufenburg line itself died out in 1408, leaving these early deniers as the sole numismatic record of a collateral branch that never achieved the dynastic dominance of their Austrian cousins.
