The decision
Is Underground Lake worth grading?
Only if you are at least 13% sure it will gem.
A 10 nets +$856, but a 9 nets −$125. Below a 13% chance of a 10 you are expected to lose money submitting — which is exactly what Mintachu's grade prediction estimates for a specific listing.

Fee uses PSA's value-tiered service levels ($150 for a card worth $1,013 graded); shipping and insurance are extra. Break-even assumes the copy comes back a 10 or a 9 — a lower grade is worse than either.
