I recently purchased two old wooden poker chip boxes, one of which still has "Triangle Brand Poker Checks" visible on the end as you can see in the picture. I also found an article from 1902 that mentions Triangle Brand poker chips.

The boxes are full of plain 1 1/2" poker chips, and I was wondering if there was any way to determine if the chips are original to the boxes or were added later. If you have any ideas, I'd love to hear them.

Thank you for your time.
