Showcase #30 Value: An 8.0 Worth More Than an 8.5

A lower grade outselling a higher one once is bad luck. On this comic it has happened repeatedly, and the reason is worth more to a seller than any single figure on the page. Showcase 30 value moves on volume, not condition.

This is Aquaman’s first solo tryout, from February 1961, twenty years after he first appeared as a back-up feature.

The tryout that led to a title

DC ran Aquaman through four Showcase issues, numbers 30, 31, 32 and 33, before giving him his own comic in 1962. This is the first of the four and the one collectors want.

None of the four is a debut. Aquaman starts in More Fun Comics #73 back in 1941, sharing that issue with the first Green Arrow, and that comic sits in a different price bracket entirely.

So this comic occupies a specific and narrow position: the start of the run that got the character his own title, two decades after he actually debuted. That is a real claim, and it is also a complicated one to explain in a listing, which is part of why the market for it is so thin.

To identify it: 10 cents, February 1961, the Showcase logo. Numbers 31 through 33 continue the tryout and sell for noticeably less.

When the ladder stops behaving

This book has no coverage in CGC’s auction reporting whatsoever, so none of these prices is a link. Heritage and eBay are the record.

Look at the 8.5 and 8.0 lanes together. An 8.0 brought $3,120 in November 2020 and $2,520 in February 2022, while an 8.5 brought $2,880 in December 2023 and $2,040 in April 2024. The lower grade outsold the higher one in two different years.

Then in October 2024 an 8.0 brought $1,200, less than half what the grade did four years earlier. Between them these lanes have produced $1,200, $2,040, $2,520, $2,880 and $3,120 for essentially the same comic.

The 9.2 above them is the only lane with any consistency: $10,500 in July 2020, $10,500 in April 2021, then $7,800 and $7,200 in March and April 2024. Firm, then down about a third, but never chaotic.

And a single 9.4 sold for $20,400 in July 2024, with nothing at that grade before or since to compare it to. On a book this thin one sale becomes the entire high-grade record, and it should be treated as a fact rather than a level.

As with everything on this site, those figures come through CGC’s reporting of other companies’ auctions and Heritage’s own published results. GoCollect and PriceCharting track Showcase #30 independently, and if their numbers disagree with mine it is worth finding out which of us is wrong.

Showcase #30 value in every grade

206 sales tracked back to 2003; here are the three freshest in every grade.

Every row above is a documented sale, verifiable in Heritage’s public Showcase issue index and in CGC’s published auction reporting. No lane above 8.0 holds more than five sales, which is why the inversions above happen at all.

Steady, cheap, and easy to quote

Below 7.0 this comic finally behaves. Thirty-two copies have sold there since January 2025 and they line up the way a ladder is supposed to.

From February to August 2026: a 7.0 brought $626, a 6.5 brought $480, a 6.0 brought $540 and another $439, a 5.0 brought $575 and another $439, a 4.5 brought $395, a 4.0 brought $414 and another $275, and a 3.5 brought $179.

Two 6.0 sales at $540 and $439, two 5.0 sales at $575 and $439. There is still spread, but it is a couple of hundred dollars rather than the multiples the graded lanes produce.

If you own a readable copy of this comic, the number is somewhere between about two hundred and six hundred dollars and I can be fairly precise about where. If you own an 8.0, I genuinely cannot, and this page is the reason why.

Selling a Showcase #30

1. Do not sell it as a debut. The character starts in More Fun Comics #73 in 1941, and that comic is in another price bracket.
2. Ten cents, February 1961. Showcase #31 to #33 continue the tryout and sell for less.
3. Expect a wide range in the eights. Those lanes have produced $1,200 and $3,120 for adjacent grades.
4. Sell into an auction if you are high grade. With this few sales, a private listing has almost nobody watching it.

Send photographs and I will tell you whether your copy is in the part of this ladder I can quote precisely or the part where nobody honestly can.

Send photographs and I will place your copy in its grade lane against the same recent sales you can read above. Where you take it next is your call, and the options for selling in Southern California are worth knowing either way.
