The thing is that 50c/$1 games are an awkward spot for chips. You could just do 1/1, but I feel the loss of quarters bumps up betting a bit, and as we know this is a game of exponents which can get big in a hurry. But 50c chips are confusing, and quarters seem like a waste.
What would work well are 50c pieces and $2.50 pieces, but as with tourneys, people have difficulty with that kind of thing. Or just use 50c and $1 chips, it's not really THAT big of a deal. I tend to over-analyze these things.
If you're going to do 1/1, then you don't really need more than one or two two stacks of dollars per player. The rest should be fives, because those will be the primary betting chips.
