You wouldnt instinctively think card stock makes a lot of sense for money tokens, but I think they genuinly rock.
Others talk about their uses in board and card games, and I'm with yall there.
But if you do pen and paper roleplaying, set in any sort of science fiction setting, these are amazing substitutes to give your players. It feels difrent when you have a stack of cash, eather than a scribbled number on a sheet of paper.
Genuinly reccomend it. My only issue, is that there arent more of them, and more of them in higher denomination values. Though they are cheap, so bulk buying them isnt that bad, unless your own wallet is already hurting.
Be mindful of that, but these are great if you want em.
