Old School C-Mold Chips (1 Viewer)

I recently came across a bunch of C-Mold chips, and I was interested to know if these chips can take a label or if they were only hot-stamped. Can they possibly be milled? The chips I am looking at are currently hot-stamped. I am including a picture from the poker chip mold identification website for reference. Any information would be appreciated!

Anybody with information?? Thanks!

Sorry, never came across these before. I thought "C-mold" referred to a pattern that looked like crested waves or a bunch of cursive C's joined together.

For the sample picture above, they used a pencil on the chip in order to see the fancy “C”.
