The openingWhy this idea is overlooked
Generic price-comp tools already exist, so people miss the distinct, net-new question: not what a card sold for, but how much the grading label itself changed the price and the speed of sale. The dominant grader commands the highest resale multiplier largely through a self-reinforcing liquidity effect (buyers search its comps, which drives demand, which drives more submissions), and nobody sells that liquidity premium as measurable data. A platform that quantifies the cert premium and liquidity by grader is a different product from a price-comp tool.
