I have some chips that I know are antique, but I'm having trouble finding any information on them. They feel and sound like plastic and have raised numbers and edges (or recessed inlays, whichever way you want to look at it) that indicate production in a mold. I ran an image search on the pictures attached and found this article from the National Museum of American History which dates them to the 1890's. This is way earlier than I expected with the color scheme, which feels like late 50's / early 60's. The only other hits were a couple eBay listings that included similar chips without any information.
One of the most interesting characteristics of them to me is that the numbers (which I assume are denominations) are 1, 5, 15 (not pictured), 55, and 100. This seems an odd choice to use 55 instead of 50 and indicates to me that there might have been a popular game that scored to 55 points.

Any info or insight is appreciated.
