One of the items that make it incredibly difficult is the disagreement on what the XXI found on my pre-reform antoninianus and also on some (not all) of the post reform follis signifies. It has been suggested that it is a ratio of 20 to 1 (XX to I) bronze to silver within the coin [12] or that it means that the coin was valued at 20 of some denomination to 1 antoninianus. Sutherland makes the case that both the denarius and sestertius survived into the third century as a unit of account and that when Aurelian first introduced this symbol he was declaring that 1 antoninianus = 20 sestertii = 5 “denarius communis” (this being the pitiful descendant of the mighty denarius of republican fame)[13]. Sutherland’s view makes sense if the aim was to head off potential inflation and the silver content argument makes sense in that the measured silver content of post reform folli based on metallurgical analysis fall within a reasonable tolerance for the theory. If Sutherlands view is correct the continued use of XXI at some mints may have been continued in part to signify that the new follis was now valued at what the old antoninianus had been. The old antoninianus (and post reform radiates of similar size) were now worth 2 denarius communis which is likely not less than what they were trading at in any case.[/QUOTE]</p><p><br /></p>
