Being new to this, I posted a while back on the strike point but didn't have any images.

Approximately 12 years ago, I came upon a small stash of the stuff, 1/5/20/25/100.

Anyway, I've heard that there are some Silver Bird chips that are counterfeit. Are these? Also, any idea what they are worth? I've got a very nice set for poker but just wondering if it's worthwhile to look for about 8-10 $1 chips or try and sell/trade it.
Thanks!
