Me and my friends have been playing a downright ridiculous amount of runebound since it came out, so much so that the enemy combat tokens have visible wear and tear on them. Fortunately, it seems that the tokens are the exact size of swedish 5-crown coins, which means that finding coin caps for them is pretty easy. The ones I bought were the No. 303522 29mm Lighthouse/Leuchtturm coin caps and the tokens fit perfectly in them and look great. Figured I would share it in case someone else was having the wear & tear problem, wanted their tokens to be shinier or just prefer the feel of plastic rather than cardboard.
Excuse the grainy picture, my iphone 4 was the only camera i had on hand.
