This chart illustrates the relative size difference between different denominations. The average diameter of each denomination determines the size of each point as well as its position along the X Axis. As tetradrachms vary significantly in weight and diameter depending on the weight standard and other factors, they have been split by AR (silver) and BI (billon) to better represent this variation in size.
If using a mobile or tablet and the chart is truncated, scroll to the right to see the full chart.
The table below shows the aggregated data used for the above chart and the variation in both weight and diameter. A column on the right indicates how many coins from my collection I have for each denomination. Denominations with fewer than 5 coins should be taken with a grain of salt as this is not nearly enough to represent the true variation.
