OK, so... I've thus far drawn a line and kept my collection to just coins and not allowed myself to get into banknotes or stamps, etc. I have a few notes from countries that I've traveled to, and I have the previous design series of US bills tucked away, but it's not something I've pursued. But this forum and seeing people's photos of beautiful banknotes is tempting me. And it is true that when you look at one's collection of, say, WWII-era French coins, you're only seeing half the picture of what money was like at that point in history. So, I'm thinking of getting my feet wet with some banknotes from my favorite countries and historical time points.
What's the best way to get started? Should I pick up a used copy of the Standard Catalog of World Paper Money first? Is it worth buying a bulk lot of banknotes off eBay the way I did when I started with coins? What kind of price per note do you usually try to stay under?
