1) Spinetti's, and others, sell these chips as Fantasy chips. I did not see any indication that the chips in your store were Fantasy chips.
2) As Fantasy chips, others sell these chips for minimal amounts, your chips are priced much higher. But you are free to charge whatever you want to.
3) The chips that others sell do not look like any real casino chips, the chips in your store look like the inlays were copied from real casino chip inlays and perhaps modified.
Image of the real chip is from the ChipGuide.
