Value history

grailworth's fair market value: what a copy at each grade is worth today, from this issue's market and how value moves with grade across every comic we track. Bold: our firmest values. ^*Rough: a looser estimate. +$: worth grading, a raw copy at that grade gains this much slabbed by CGC, after the fee and shipping. Pick a grade for its value history and the most to pay for a raw copy you'd send to CGC.
