A $50 (100 bb) buy-in is automatically short stacked in a 0.25/0.50 cash game, so if ordering chips, consider having chips for 200 bb (or even 300 bb) buy ins on hand for when your gang feels more comfortable playing those stakes.
Alternatively, drop it to a 0.25/0.25 game and stay at $50 (200 bb).
However, assuming you do run 0.25/0.50 and eventually go as high as 1/2 (a 4-fold increase in stakes!) you’ll need a lot more chips.
In a casino, a 1/2 game typically has a $300 buy in (150 bb)… and they are usually all $5 chips with the dealer making change with $1 chips.
$25 chips will make an appearance in some stacks, mainly as add ins or to open up space when a player has $800 or more in $5’s — they’ll trade out $5 x 100 for $25 x 20 ($500 swap), keeping 3 stacks of $5 ($300) as their main working chips.
$100 chips are rarely put in to play and are mainly used for rebuys.
Given all that, I don’t use $100 chips at all in my 0.25/0.25 home game… I only want to manage 4 denominations on the table.
And I definitely fall into the “starting stack of 0.25 chips x 20” camp.
I also prefer $20 chips for cash games and reserve $25 chips for tournament sets.
I use this PCF resource from member
@BSteck for calculating my cash & tournament sets, then tweak it based on my own preferences:
https://www.pokerchipforum.com/resources/poker-set-selection-tool.90/
So using that tool, below is my 0.25/0.25 set of 800 chips with my personal denom adjustment. You’ll see that my $1 chip is my workhorse with plenty of $5 for bigger bets and some $20 for higher buy ins, add ons, top ups and rebuys.
I’ve also added a note showing how many more $5 and $20 chips I would want if I also ran a 1/2 game, mimicking how a casino would do it. You can see how big the set gets when not putting $100 chips into play, but again, this is how it’s done in a casino at those stakes.

I hope this helps and gives you some ideas for your own game. Give that set selection tool a try to get you a starting point to work from.
