Crawford hates the term aes signatum, but the more I work with them the more I seem to default to this name. It seems so much more succinct that Roman Currency Bars.
Black are specimens known to Haeberlin and discussed as aes signatum by Rudi Thompson 1957.
Berlin RRC 7/1 is a half specimen but appears nearly exactly half, so given here as it’s putative whole weight. Velitrae RRC 4/1 is reconstructed from Townsley’s observations and converting to metric.
I follow Ghey, Leins & Crawford 2010 in giving amphora/spear-head the putative RRC number 12/2.
