I'm not super fond of Swedish coins - I think they're rather bland and boring in comparison to other countries' coins.

It's happened more than once that I nerded out over cool coins and spent hours looking through different ones on wikipedia. Like look at these japanese tael sycees, are they not a thing of beauty?
Edit: Or this Chinese Yansheng coin!
