Here's some info on Game On Chip Company's plaques and chips. The pricing info is from September 2014, so prices could have increased since then. Pricing may also vary based on the size of an order, if options (like UV printing) are utilized, or who-knows-what. But, the prices listed work as a general guideline. Sorry I don't have a price for the octagon. Lastly, be aware that GOCC offers rounded-corner plaques that match the sizes of the cut-corner plaques shown here. (I only have samples of the cut-corner plaques.) This is GOCC's cermic details page: This is meant to show the recessed middle of the cut-corner plaques: For scale/size-comparison, I've added 39mm chips: Here's how the three cut-corner plaques stack up: Here's how the "business card" plaque compares to one of Sunfly's plaques: The business card plaques are the same thickness as the chips and octagon. The three cut-corner plaques share the same thickness but they are thicker than chips. Here's a stack of 10 plaques with a barrel of chips (20): A stack of 12 plaques is as close as you can get to 20 chips without going over: Personal bias alert: the business card plaque has a smooth finish and a high-pitched plastic-y sound to it that I'm not fond of (sounds cheap), especially in comparison to the other three plaques that have a slightly textured/satin finish and a satisfying "clack" when stacked or dropped in a pile. I'd gladly order more cut-corner plaques but I don't think I'd ever order the business card plaques. If anyone has more info on GOCC please post it here so we can have a comprehensive guide to GOCC. Thank you!
