   "q": "Is it worth grading Swampert 9/106?",
   "a": "At $40.43 plus PSA Standard $59.99 ($100.42 all-in), against a $802.85 PSA 10 and a $195.50 PSA 9 each netted for eBay's published selling fee, a PSA 9 alone clears the cost at $195.50 before fees, so no tens are needed. The registry's recorded gem rate is 31%. Shipping and insurance, to PSA and to the buyer, are not counted. That is arithmetic on recorded figures and published fees, not advice."
