One CGC 9.4 of Adventure Comics #260 sold for $26,400. The next documented grade down is an 8.5 at $2,500. Between those two numbers there is nothing at all in the record, and that gap is what this page is about.
The CGC 9.0 of Batman #155 has twelve documented sales and every recent one is lower than the last, from $4,080 in January 2024 to $2,200 in March 2026. That is the clearest single-grade decline in this batch.
The CGC 9.0 of Doctor Solar #1 has gone down over six years while the 8.5 beneath it has more than doubled. The two grades have nearly met, which is unusual enough to be the most useful thing on this page.
Flash #139 is the first Reverse-Flash, a character three television seasons and a film have put in front of millions. The comic itself still sells for about four hundred dollars in the grades most people own.
Flash #110 has the first Kid Flash and the first Weather Wizard in the same issue, and only a hundred and sixty-one documented sales behind it. The high grades are thin enough that a single 9.6 sale defines the whole top of the book.
A CGC 9.8 of Teen Titans #1 brought $10,158 in 2016, $31,200 in 2021 and $11,400 in 2025. The whole boom and the whole retreat are visible in three sales of one grade, which is rarer than it sounds.
Superman #199 is the first Superman and Flash race, a story DC has restaged for sixty years. It is also a comic where ninety-one readable copies sold in eighteen months for between $160 and $313, which is the number most owners need.
Showcase #9 gave Lois Lane her own comic before she had one, and its entire high-grade record is a single sale at each of four grades. This page shows all of them and says plainly what they can and cannot support.
A CGC 9.0 of Brave and the Bold #34 brought $9,600 in April 2022 and $3,360 in September 2025. Six documented sales trace that fall, and the grade directly above it did not move at all over the same three years.
In August 2026 two CGC 9.0 copies of Scooby-Doo #1 sold on eBay for $10,999 each. Identical grade, identical price, days apart. On a book with only 110 documented sales that pair is worth more than everything else in the record.
