As several have noted - these are "paranoid" branded chips. 1900 - 1950's, most likely 1920's ish.
For their time, these were top of the line (especially the custom monogramed ones). Original cost in today's dollars, a couple of dollars/chip. These were not grandpa's dice chips. They were grandpa's holy grail chips. Sadly, these are not much in demand today. Perhaps if you have provenance showing these were from a roaring twenties illegal card room - then you could be value and buyers.
Paranoids aren't rare. Vast numbers are out there, scattered to the winds of time. They aren't worth that much. Maybe $0.25 - $0.50 each. Old does not mean especially valuable.
It can be a fun adventure to piece together a playable set off of
eBay, except the OP does not need to do that. Putting together a set as shown in the OP would not be easy.
The chip case is very nice. That's consistent with the original value of the chips.
I hope these have seen interesting times. Maybe there are family stories about how things were "back in the day". Someone spent a relative fortune on the chips and case. If only the chips could speak, what amazing tales they might have! -=- DrStrange
