2019 MARKET UPDATE: TIME TO GET YOUR FEET WET?
The severe kicking given to most DC Comics characters in the past 12 months seems to have missed this issue, and I see positive signs.
That should be tempered by the fact that the Aquaman movie is still in theaters...
24 percent is not huge, but it's a big result compared to so many DC back issues. Enough to tempt you to take a profit while the going's good?
I'd hate for this book to sink to the seabed in a few weeks and leave your investment wrecked.
2018 MARKET UPDATE: SHOWCASE ISSUES DOWN, BUT NOT OUT
The Justice League movie had a very positive effect on prices of books like this one, under-valued for a long time.
Prices have softened since, but it remains a book to hold.
2017 MARKET UPDATE:
Investors who bought this when we featured it last year will be pleased. The book continues to appreciate in value, and while Aquaman might not be everybody's cup of seawater tea, his Silver Age books are all relatively warm in the market.
They have been under-valued for too long, which doesn't hurt recent sales. A rare book in high grade, and there's plenty of support for mid-grade and nicer copies when they do turn up.
What a difference a couple of years makes! Marvel blazed a trail with a blitz of superhero movies, many of which created key issues from former dump bin stock items.
DC played catch-up, and now there are at least half a dozen DC movies in the works.
Aquaman is a Golden Age mainstay who was rebooted in this vastly under-valued and under-rated Silver Age key issue.
Not only is it (arguably) his first appearance since the Golden Age, the issue introduces Aqualad, who later goes on to be part of the Teen Titans.
Showcase #30 is a tough book in fine or better shape.
