First post, so take it easy on me if this has been discussed before.  Didn't find anything in search.
So anyway, after years of dreaming about building a mame cabinet I'm finally beginning to get serious about it.  I've been thinking about my CP layout, and I had an idea which I thought might be kinda cool.  You know how people used to line up quarters on the bezel to "call next".  Well, I was thinking about putting my coin buttons on the bezel and maybe gluing a quarter on the top of them to replicate this look.  Has this been done before?  Do you think it would look cheesy?  Any potential problems with doing this?  
I'm a total noob on this stuff.  I don't know electronics or woodworking, but I'm pretty handy and I plan on teaching myself as I go.
