It was the ancient Greek historian, Herodotus, who told us the story about the invention of coins in Lydia (in what is modern-day Turkey). But Herodotus was clearly so surprised and impressed with this new idea that he didn't talk about a lot of the questions we might ask ourselves about this new invention. For one thing, I don't remember him telling us what the purchasing power of the "Lydian lion:" coins might have been. 1. Were they very valuable (let's say like a $100 or $1,000 bill might be today? Or were they low-value like a loonie or toonie? 2. Did the Lydians have more than one kind of coin? [as always, we are interested in facts that we can verify]. PROVIDE ONE SOURCE/LINK!
