Usually they're around 9g, but his might be different. I weighed 3 colors. Two were 9.18 and my red is showing 9.3.
I may be interested in the red if they match mine. Though might not know about my money situation for a couple weeks (waiting for a bill from a fabricator).
I tried to buy an identical set off of Facebook and the guy wanted $75 bucks total for all 1000 chips. I don't know anything about this chip but now I'm wishing I would have purchased them.
