Watching vlogs of Andrew Nemee and others that play at the Belagio $5/10 game the workhouse chips is actually the $10 chip.
When they buy in for $1500 they get a rack of $10 and the rest in $100's.
The $10 and $100 are basically the only chips used for play and some big chips when players rebuy from their pockets.
I was going to mention this, too. Glad I read all the way down first. I thought it was strange when I first saw the $10 chips being used in some of his vlogs, but after I saw it in play, the idea warmed up to me. In those vlogs, I seem to recall players only having just a few $5s in their stacks, like fewer than 10, and maybe even just 2 or 3, but that's a raked game, of-course, so a lot of those $5s end up in the toke box. The Aria has a similar orange colored $10 chip that the Bellagio uses, but I don't know what chips Aria uses in their $5/10 game.
Of course, the whether a $10 even makes sense depend on what denoms are available, or what chips you already are using. Other $5/$10 games use $5s, $25s & $100s.
Another related item is if there is going to be a dedicated dealer, dealing for tips, or a rake, etc. then some $1 chips and maybe more $5 may be needed, although these could be managed and distributed out of the dealer tray. And in $5/10 games, the $1 chips generally don't play, they're just there for tips -- they don't count as all-in, but this might be true just for single $1 chips below increments of 5.
If you want more chips with the same bank then you could always go with a $1000 chip instead of a $500.
I like this idea. I've seen the $5/$10 game at MGM National Harbor (buy in, is $700-$2500, IIRC), and I did not see any $500 chips on the table, but they used $1000s (which are oversize, and more visible). One player broke out a couple $500 chips to buy-in, and the dealer/floor brought 2 barrels of $25 chips from the cart, rather than having a player next to him with a huge stack make change. I got the sense that the dealer/floor wanted to keep the $500 chips off the table, so the chips wouldn't be accidentally be confused or stacked with the $100 chips since they are the same size, but the $1000 chips were OK because they are oversize and bright orange.
