Box → Singles

Grading economics — coming soon.

Activates with the optimizer + pop data integration.

The Box → Singles panel ties this product back to the per-card grading optimizer: expected pull rates × probability of each grade × current PSA / CGC / BGS / SGC / TAG comps, netted against fees and shipping. The output is a verdict ("SEALED IS UNDERVALUED", "FAIR", "OVERVALUED") so a serious investor can compare a sealed box's spot price against its expected singles EV.

Activates the moment pop_reports rows land for the cards in this set.
