There’s always poker chips for giving out plot points.  This is apparently the suggestion for Deadlands.  For Battlestar Galactica, I intend to use the myriad of spent 5.7x28mm casings I have from my P90 and FiveSeven handgun (the platform for the colonials’ pistols.)

I tried it out last night for our Hollow Earth Expedition game (although it really should have been .45acp) and the players seemed to love it!
