I think for me, it was the history of money, in all it's various forms. What happened when superior money was introduced, and how those who continued to use the inferior money lost out, over time.
Also the concept that money must be SCARCE, at least good money. And hard to produce. Considering that our fiat currency now is just printed, on paper, or generated by a few keystrokes digitally, this was a novel idea for me. But of course it makes so much sense.
