   "q": "Is it worth grading Mewtwo 51/108?",
   "a": "At $2.96 plus PSA Standard $59.99 ($62.95 all-in), against a $200.25 PSA 10 and a $40 PSA 9 each netted for eBay's published selling fee, you need a 21% chance of a 10 to break even. The registry's recorded gem rate is 23%. Shipping and insurance, to PSA and to the buyer, are not counted. That is arithmetic on recorded figures and published fees, not advice."
