The Quarter-Maiorina denomination
The quarter-maiorina was a fractional denomination struck in bronze rather than billon, in contrast with the half-maiorina and the maiorina.

The Maiorina was a billon coin replacing the heavily reduced centenionalis introduced by Constantius II and Constans in AD 348.

It was struck on two weight standards - 5,2 and 4,5 grams - but by the end of Constantius' reign in AD 361, this coin too had been reduced to a mere 1,9 grams.
