Recorded sales by grade · how this summary is built+
Newest recorded sale: 2026-09-12. This summary describes stored history.
Inclusion
All 4 recorded eBay sold (completed) listings in this historical sample, grouped by grader and grade. Asking prices and active listings are never counted.
Outlier handling
Within any grade that has four or more sales, a price below one-third of, or above three times, the within-grade median is set aside before the median is taken. No sales were set aside on this rule for this item.
A comic sale that sold for under a third of the median of this issue's lower-grade sales is also set aside as a probable reprint, facsimile, later printing or restored copy, since a higher grade of the same book should not sell for less. No sales were set aside on this rule for this item.
| Grade | Sales | Included | Set aside |
|---|---|---|---|
| CGC 9 | 2 | 2 | 0 |
| CBCS 9 | 1 | 1 | 0 |
| CGC 8 | 1 | 1 | 0 |
