Wow you got these delivered already? That was quick. Still major regret not snapping these up on the For Sale post. I was trying to think of a theme or two that'd go with the A-mold. Of course by the time I thought of one or two, you had already snatched it up. Good pickup! I agree with
@Colquhoun you don't need both .25 and .50 chips. Have the denoms be 4-5x larger than the last.
My regular group plays .25/.50 but I do occasionally play in 1/1 or 1/2 games. This was my plan for them, breakdown-wise. I was going to use 120 whites as $1s and 200 reds as $5s (round numbers), standard. That'd make the bank $1,120 so far.
Then I'd take 80 greens and make them 25¢ chips, and 30 blacks and make them $20 chips. That'd add $20 and $600, respectively, to the bank for the 25¢/50¢ game. I'd use these chips exclusively for these stakes.
I'd also make 40 greens into $25 chips, and 20 blacks into $100 chips, which'd add $1,000 and $2,000, respectively, to the bank for the $1/$1 or $1/$2 game. I'd use these chips exclusively for these stakes.
Alternatively...
I would create a label for the green chips that featured both "$" and "¢" on the chip (maybe make one symbol more prominent on one side of the chip and vice versa, but have the symbol on both sides), so they could act as both 25¢ chips and $25 chips. Then I'd split up the black chips similarly to how I laid out above, with 30 of them being $20 chips and 20 of them being $100 chips. Then for the 25¢/50¢ game, the greens are 25¢, and for the $1/$1 or $1/$2 games, the greens are $25, and only use the appropriate black chips for each game.
(For security purposes, I'd account for every chip at the end of each gaming session. Hopefully everyone you play with is a trusted friend, but definitely don't want someone palming a chip worth a quarter one night and then turning it in for a quick $24.75 in profit the next night!)
