For a one table cash game, .05/.10 blinds with these denominations:
.05 - 1 rack distributed to players - first 5 get a barrel each and make change for others
.25 - workhorse chip #1, 1 barrel per player minimum (I prefer 2 barrels/player)
$1 - top each player up to $10 with these, your second workhorse, and use them for rebuys if you have lots, if not use $5s for rebuys
