I just do rows of 5 credits each, arranged into a neat matrix. That way, I can tell perfectly well how much money I have at any given time, without telegraphing much. Also gives me something to fiddle with that isn't shuffling cards in hand (that shit drives my wife nuts).
This, so much this. Really hate it when people do that, to the point of asking them to re-organize so that I can see how many credits they have without explicitly asking them. Stuff gets super-weird if they play Making News, have around 3 credits and use credit tokens for the recurring ones as well.
(in my tournaments, the "get your goddamn tokens in order if you're gonna play here" bit is part of my standard TO opener)
