Should I grade this?

Grading with PSA pays if your copy has better than a 19% chance of a 10.

29% of the 2,246 copies PSA has graded got a 10. People mostly send their cleanest copies, so a typical raw copy's odds are lower.

Raw (NM): $38.92; TCGplayer

If it misses: $52.54; below 10, by PSA's grades
