This is one of the more entertaining threads I've read on here...

I think there are two discussions going on here, and they are being treated as a single thing:
The first issue is the copyright from a legal perspective. That one is pretty clear cut: if you are using someone's artwork to make your tokens, you are infringing on the owner's copyright. People who don't deal with copyrighted material may disagree, but that doesn't change anything.
In the end, the real question is "if someone sends you a Cease and Desist, do you feel confident enough to ignore it and eventually (pay to) fight it in court?" For a project of this scale I would assume the answer would be "no."
The second issue, which I think is more relevant, is whether you ethically should be able to do use the images, and if this form of infringement causes any real harm. That's (obviously) a lot more a thorny question.
I'd throw my 2¢ into the ring about the rights of artists, but I'm not giving a dime to Lucasfilm or John Williams when I use their music for my game's intro crawl, so there you go.
