Key Collector describes an acquisition guide based on up to ten ungraded secondary-market transactions in a month, with an approximate 10–15% reduction. Its public issue pages do not disclose each book’s underlying sale dates, sample size or most recent valuation update. “Checked” means when the displayed figures were inspected, not when every underlying sale occurred.
The original USD figures are retained in the evidence appendix. GBP = USD ÷ 1.3265, rounded to the nearest pound, using the Bank of England’s displayed spot reference for 23 September 2026. Currency conversion does not establish a UK market price. Small rounded figures can be below ordinary shop prices; they do not mean a copy is available at that price.
Low, Mid and High are broad raw condition categories. They are not grades 2.0, 6.0 and 9.8, and the High figure is not a pristine-copy ceiling. Certified sales, scarce variants, incomplete copies and restored copies need separate comparisons. Shipping, import costs, purchase fees and eventual selling costs are additional.
Use these numbers to decide what to research next. Before paying, compare recent completed sales of the same issue, printing, price edition and comparable condition. Asking prices and unsold listings do not establish value. For a substantial purchase, examine clear photographs of the front, back, spine, staples and interior.
We have not established a matched ten-year raw sales series. A defensible uplift would require like-for-like editions and condition, comparable sale samples at both dates, and a clear treatment of fees and inflation. We therefore publish no ten-year percentage or promised return. These are collecting choices with resale risk, not guaranteed investments.
For Hulk #1, #2 and #181, the generic raw guide bands are orientation only. Authentication, exact grade, completeness and restoration can outweigh the apparent precision of the displayed figure. The high column is not an estimate for any unseen copy or a ceiling for exceptional copies.
