2018 MARKET UPDATE:
Steady gains and a couple of record-breaking prices catch the eye this year.
If you bought this book three years ago, you're happy. Now it's a little more difficult to find value, but long-term I am still bullish on SC #4.
Here are recent sales.
2017 MARKET UPDATE:
If hotness is a function of rising prices and turnover in the market, then it's the latter that has forced us to drop SC4 a few places on this year's 100 Hot Comics.
Unfortunately, it's such a scarce book that it seldom changes hands. Surely, if there were as many available as Amazing Fantasy 15, it would be #1 on this list, or close to it. Here are some significant recent sales:
The Flash is hot property at the moment, thanks largely to the DC Comics TV series. Barry Allen's first appearance also is the book which is credited with beginning the Silver Age of comics.
Along with these good reasons to invest in this tough book are the Showcase series itself. A very tricky run to put together if you're particular about condition.
Other entries on the Hot 100:
You're going to struggle to afford a nice copy of Showcase #4. We drew the line at CGC 3.0, which is still thousands of dollars.
Aim for one with the nicest eye appeal possible.
