They're definitely two different types of chips. But if the boxes are to be believed, they're both from Langworthy & Co, in this case meaning sold by Langworthy rather than manufactured by Langworthy.
Langworthy did manufacture some chips of their own, but they were injection-molded plastic. Both your HHR chips and the die-cut inlaid chips in that other post are compression-molded and were probably made by Burt. It's possible the die-cut inlaid chips were made by USPCC (the US Playing Card Company) depending on how old they are. Pre-WWII, USPCC was the main producer of those types of die-cut inlaid chips, maybe even the only one? In 1947 Burt bought all of the USPCC chip-making equipment and may have kept making those chips for a while.
But your HHR chips were definitely Burt, or maybe ASM if they are newer than 1988. I'm pretty sure USPCC wouldn't have had the HHR mold to make those chips, and I'm not even sure they ever made any chips in that style, i.e. with a molded edge impression.
Anyway, these are almost certainly essentially the same as chips you could buy from
CPC today.
CPC uses the same materials, equipment, and processes as ASM did (because they bought them when they went out of business), and ASM used the same materials, equipment, and processes as Burt Co did (because they bought them when they went out of business). So these chips were probably made by Burt many decades ago, but are nearly identical to
CPC chips today. Getting 700 for $75 is a treasure trove. You just have to decide what you want to do with them.
