I was considering buying some of the Mayday games Euro-tokens for use in Kingsburg, but I found that I would have needed three thirty dollar sets to get enough gold to make that work, plus then I'd have a lot of extra stuff. But now they've got Kingsburg specific quantities available here
and they're on sale for $14.95. That works for me!
Full Disclaimer: I had asked them if they might be able to make such a set so I wouldn't have to buy three sets of the Euro-Tokens, and they did!
