Counts and Ratio of Select Words

These stacked bar plots show the number/ratio of coins from [SOURCE] with each bar representing the number of coins produced containing the [WORD] crown by each authority/emperor/emperor(s) displayed ordered chronologically. Each bar of the count plots is stacked by the number of coins made of each material.
