The weights varied from slightly less than one gram to almost three grams, but most seem to be centered around one scripulum, a Roman measure of weight which equals 1.13 grams. A distinction between quarter-folles and "denarii communes" may not exist, but the term "Quarter-Follis" is the most commonly used. Since the follis (q.v.) was first struck at between 8.5 and 11.0 grams, it is uncertain that a fractional quarter was meant. After the follis was reduced in weight the ratio comes closer, but still is hardly exact.
They were only intermittently issued during the period and were never common, judging from their scarcity today.
