1000 chip set.
0.50 * 100
1 * 400
5 * 400
25 * 80
100 * 20
Total Bank overall 6450
Total bank in 0.50/1/5 2450. (meaning you would need 24 buy-ins of 100 before you even tap the larger chips.
When I host this stake I usually start players with 6/12/x of 0.50/1/5 with x being the number of 5s needed to make the desired buy in. All players can have around 2 barrels of fives in a single table game and more like one barrel with a two-table game.
You could also consider eliminating the 0.50 chip and going with 1-1 blinds and add another 100 fives to my suggestion. The only downside to this is then you cannot downstake to 0.50-0.50 if you need to host smaller.
Good luck,
