Map created using AWMC: à-la-carte Map to which it links. [FYI – runs best for me in firefox rather than other browsers.]Crawford CMRR discusses the cast currencies of Italy in five groups (p. 43-46):
an as of about 300g maybe from 1st Punic War: Tarquinii, Tuder, Reate, Praeneste, Carseoli, and Firmum
a heavier as (350-450g): Ariminum, Hadria, Vestini, another unidentified mint maybe Asculum Picenum
an as of about 300g followed by reductions probably from 2nd Punic War: Luceria and Venusia
reduced as from rebel communities during 2nd Punic War: Volceii and Meles
issues of Etruria and Umbria (including Iguvium on map above) on 200g standard from time of 1st Punic War
He summarizes circulation and weight standard thus:
RRC 14/7. Semuncia circa 280-265, Æ 14.36 g. Acorn. Rev. Σ. Haeberlin pl. 40, 23-27. Aes Grave 40. Sydenham 14. Thurlow-Vecchi 7. Historia Numorum Italy 274.
Crawford say on p. 40 of CMRR:
Andrew Burnett acutely points out that the weight standard of the semunciae of the first issue of cast bronze [sc. RRC 14] makes it clear that they represent a point of transition to the second, which is heavier than the first (the reasons are mysterious).
I’m still unclear on the whole subject (hence the blogging about it…). Does it mean that the heavy semuncia of RRC 14 shows a tendency to think about the pound as heavier than 322g?
A 322g as should have a 13.42 ish semuncia as its the 1/24th denomination.
Not a large sample size but woah that’s some variation in the data. And three, maybe four, of these seven specimens weigh enough to be a plausible weight for a uncia in the same series.
So what about the ‘heavy series’ RRC 18, no semuncia for comparison but we do have an uncia. And remember on weight standard of 334g we should expect as weight of about 27.83 g for the 1/12th piece.
Holy variation, batman! But again four of our RRC 14/7’s would fit comfortably into the lower end of this observed data set.
Time to step back and ask a really basic question. How do we know its a semuncia and it goes in this series? I opened up Crawford’s list of the Nemi finds. Not one example of RRC 14/7. There are for context 50 specimens of other RRC 14 denominations including 11 uncia (weights for the four specimens in Nottingham = 28.19, 27.04, 26.77, 27.46, cf. weights of RRC 18/6: 19.96, 29.09, 24.86, 28.55). Jaia and Molinari 2011 (link above) have an appendix of all the hoards of just RRC 14 and 18 aes graves (i.e. those that should have an early closing date). No semuncias. Not surprising really, small change isn’t the most desirable for hoarding.
And I’m not really less confused that when I started writing this post, but I do have a mad urge to start collecting a big spreadsheet of specimen weights. I’ll resist for now.
