Back when my group in Utah was playing The Dresden Files RPG, I wanted to try something different than my usual beads or stones for Fate points. I initially considered the official Fate coins: They’re lovely, but also not cheap, and like beads/stones they’re all the same.
And then I thought, why not just use actual coins? But not the same coin; not a roll of pennies, economical as that solution would be.
A few eBay searches later, I figured out that I didn’t want any tokens and that I did want circulated currency (more character). For about $18 shipped, I bought a pound of “world coins,” about a hundred coins with just a couple duplicates.
I like coins, so there’s that, but they also seem perfect for Dresden. They’re often rich in symbolism, like many things in the Dresdenverse. They symbolize the diversity of a large city. And they’re actual currency, a handy reminder of the mechanical currency in Fate — and one that feels good to hold up when offering a Fate point.
They worked great in play. We always had more than enough of them at the table, and the purse I kept them any took up hardly any space at all. While that campaign has ended, my coin purse sits on my shelf of game aids, ready to serve in some other game.
 I also learned that “that coin smell” is actually the oil in your skin reacting to the coin, not the coin itself. Coins don’t generally smell like much until you’ve handled them a bit.)
