A Roman Plum Bob arrived this week. It is one of the smaller ones I have. It is about 1/8th of an inch short of 2" long and weighs 61 grams. My new PB and two already in the fold. Notice that the middle weight, 46 grams, looks a lot like the weight in the A shaped level on the reverse of Martin's coin: L Papius Denarius Serratus Obv:– Head of Juno Sospita right, wearing goat skin tied under chin. Behind head, crowbar. Rev:– Gryphon running right; in ex., L. PAPI.; in field, mason's level Minted in Rome from . B.C. 79. Reference(s) – RSC Papia 1. RRC 384/1. RCTV 311. Symbol variety – RRC 131. Babelon 31 BMCRR unlisted. CNR 1/032 and finally my M.VOLTEI.MF with a PB.
I also collect exonumia and sometime other exonumia collectors will add things to their collections that fit together. They're companion pieces and that's what you've got here!
