I have a few tokens and coins in my collection from fantasy and sci-fi genre; think Battle Star Galactic cubits… for RPG, LARPers and the like, you can take a look at Realm Coins up on KickStarter, although not as detailed as Campaign Coins it should be a nice, affordable alternative for people to use in general for all sorts of RPG games and board games.
These sort of small, niche manufacturing runs aren’t cheap and the companies that do this sort of thing (still here in the United States) with the quality one would expect are hit or miss. The closest one I found that showed promise is Wendells, Inc. out of Minneapolis: http://www.wendellsinc.com/minting/process.html
Gamer Bling has a fantastic writeup on Campaign Coins:
Gamer Bling is a numismatist. And by that he doesn’t mean that he’ a Gary Numan fan, although he is; he means that he is a coin collector, and he geeks out over coins the way other people geek out over whatever it is that they geek out about, many examples of which, like PVC statues of underclad Japanese anime girls, are things that are generally not admitted in public.
Gamer Bling collects coins. And he is geekily proud of his collection inasmuch as it has coinage from a variety of legal entities that no longer exist, like Yugoslavia, the free city of Danzig, France when they were a military powerhouse, and whatever company it was that thought the d20 Book of Erotic Fantasy was a good idea (Gamer Bling didn’t really see a need to read a guide that defined gnomes by the fact that they liked to have sex in groups, and probably using PVC anime statues as props, too).
