About 10 years ago, I came across a box of Silver Bird chips, mostly 1s, 5s, 20s, 25s with probably a handful of 100s and 3 500s, as well as some Holiday International. I've cleaned them and used it for regular poker, as well as gave some away (I used to have about $2K worth of chips).

I can't find too much information on their value or history. I probably won't part with it but I'm just curious about their value and rarity.
