Mega Charizard Y ex from Ascended Heroes ranks among the best cards to send to PSA right now. The gap between the $271.53 raw price and the $1899.00 PSA 10 price gives a 425% Return on Grading. The upside only holds if the copy grades a 10, so inspect edges and surface first.
Most grading maths asks you to guess your odds of a PSA 10 first. This works backwards from the prices instead and tells you what those odds would have to be.
The number is different on every card. It's how confident you'd need to be that this copy gems before grading pays for itself, so 20% means roughly a 1 in 5 shot and 50% means a coin flip.
Grade it if you rate your copy better than that, leave it raw if you don't.
It assumes a 9 is the worst you'll get. Centering and edge whitening send plenty of modern cards back at 8 or lower, and that's not priced in here, so treat this as the floor of the bar rather than the whole of it. Selling fees aren't counted either.
(cost - PSA 9) ÷ (PSA 10 - PSA 9)
This barely needs
a shot at a PSA 10 (1%) for this to pay off.
The PSA 9 price on its own almost covers what you'd spend, so you're paying very little for the chance at a 10 worth $1537.47.
