Varies, most of my structures start with 100, 500, 1000 & 5000's so with tables braking and chip racing 100's etc I'd just be introducing the next value, say for example 10000, but sometimes I'd just be adding more 5000's.
I do try to keep high denominations off the tables until such time as tables are more tightly managed, especially 25,000's which I would never put out early on, simply because there's far too many players roaming around.
