<div>Note:&nbsp;After 211, the monetary system underwent a slight change and here we see the standard coin, the&nbsp;denarius&nbsp;making its first appearance. At this time, the denarius weighed approximately 4.5 grams. Also introduced were several fractional silver coins, the&nbsp;quinarius&nbsp;at 1/2 the weight of the denarius and the&nbsp;silver sestertius(shown left) at 1/4 the weight. The quadrigatus (at x2 the denarius) was still being produced during the early part of this period but was soon phased out of production.&nbsp; 
 
The quinarius and silver sestertius were produced on and off until around 40 BC when the silver sestertius was phased out entirely. The quinarius continued to be produced well into the imperial period. Judging by the surviving numbers, neither denomination were mnted in very large quantities.&nbsp;</div>
