I am a bit confused. I have always thought that a Byzantine miliaresion (silver coin) was worth 24 follis. I have stated it several times, and nobody corrected me. But if I understand David Sears figure correct he is saying that it is actually worth 15 follis. Anyone here who can tell me how much worth a Miliaresion was to follis? Was it 24 or 15?
It was 15 folles. The measurement is as follows: 1 solidus = 24 keratia = 180 folles = 7200 nummi 1 keration = 7½ folles = 300 nummi 1 folles = 40 nummi The miliaresion was equivalent to 2 keratia and thus 15 folles or 600 nummi. Keratia was a unit of weight which is equivalent to 0.189 g...
Thanks @Quant.Geek - I had harbored this same question since I started collecting 40 nummi pieces a few years back.
