''Quarter-Follis' (plural: 'Quarter-Folles') is a rather ill-defined term used to denote the smallest laureate fractional 'aes' (bronze) coinage from about 294 until about 315. 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. They were only intermittently issued during the period and were never common, judging from their scarcity today.' - from Moneta Historical Research by Tom Schroer
