There's no way NAGB killed CPC demand. It's a completely different product and price point, especially w/ customization. Tina definitely did though. Can't compete with China-pricing for customs and so on.
My point, if Angel Playing Card Co. wouldn't make the chips, and if we're being honest here, the only one paying exorbitant pricing is the end buyer as the creator only paid 2-3 $ a chip, and they stayed with their "we only sell to licensed casinos" format, there's a few hundred thousand chips floating around the market that should have never been produced.
Now don't get me wrong, I don't hate that the buys got through, I love it, I hate the price gouging that occurred from the "originator and the secondary vultures that marked them up even further. But that's all in another thread.
So, I believe that they did have a profound impact because all those folks wouldn't have 100% gone to Tinas.
