Depends on starting stack size & blind structure.
Assuming 10 players....
If you start with 100BB stacks & blinds of 25/50, that's 50K in play & 50 1Ks would cover the amount of chips in play. 5Ks wouldn't even be needed.
If you start at 25/25 & 100BB then 50 500s would be enough to cover it all.
What you've got would work with 200BB stacks (10K) starting at 25/50 blinds. (or 400BB deep starting at 25/25)
With starting stacks of.....
t25 x 12
t100 x 7
t500 x 4
t1K x 7 (or t1K x 2 + t5K x1)
It's tight with a 400 chip set, but it'll work.
