I was wondering if someone could assist me, (and others), please, by providing (or pointing to) a chart that details the various denominations of Roman Republican Coinage? For example, Denarii, years of mintage, and size and weight for those years, and relationship (value) to other denominations from the same period. (2x Quinarius etc.) Also for Quinarii, and Victoriatus, (and others)? I have been (trying) to follow these but have only succeeded in getting confused. I have a number of coins from this period and whenever I think that I know what I have I am thrown into doubt by reading more information (posts). Some of mine are (silver) Imperial coinage: 20mm at 3.95gm, Denarius 17mm at 3.18gm, Denarius? 15mm at 2.10gm, Quinarius/Victoriatus? 14mm at 1.50gm, Quinarius/Victoriatus? 13mm at 2.10gm, Quinarius/Victoriatus? (Dr. Google has only confused me further.) Edit: While the 'mm' descend evenly, the 'gm' are all over the place.
