Here’s a confirmation. Marvel Super-Heroes #13 is now a major Silver Age Marvel key with no end in sight.

$350. Maybe the nicest looking Marvel Super-Heroes #13 you can find on ebay? Carol Danvers will be a huge part of the MCU Avengers going forward and will probably be their leader after Steve Rodgers(Chris Evans) and Tony Stark (RDJ) retire from the movies.

I can tell you MSH13 left the 2018 Overstreet prices behind a while ago. High grade copies of CGC 9.0 or higher sell on eBay or ComicLink (when they’re available) for $2500 and up now.

Well, according to the CGC census, there aren't that many higher grade copies out there so it's a small club by default I suppose?

And here’s a flashback scene from Secret Invasion x-over Ms Marvel #25 featuring a Skrull as Carol Danvers and Mar Vell. Might we see this scene in the movie? Drawn by Ron Frenz and inked and signed by the great Sal Buscema.

As the Skrulls have kind of made their big screen debut this week with the Captain Marvel photos, here’s a page drawn by Marshall Rogers from Silver Surfer #6 which I believe is the first time in print we see the origin of the Skrulls.

My other high grade copy.

Yeah, I also grabbed a FF#2 mid-grade a couple years ago at a relative bargain. That’s a book that seems to be slowly gaining steam.

Ah, ok. I was just responding to your phrase "closing the gap." From observing the market, the gap is widening. While MSH 12 has seen an uptick in value of a few hundred dollars for high grade copies, MSH 13 has seen an uptick of thousands of dollars for high grade copies. But yeah, I'd agree that MSH 12, being the first appearance of Mar-Vell and the Captain Marvel storyline, which I think will be heavily adapted in the upcoming movie (Jude Law's credits are "Mar-Vell / Dr. Walter Lawson), is heating up and will get hotter once the Captain Marvel trailer drops...next month?

At this point, MSH 12 is not and never will be in the same stratosphere that MSH 13 is in. If the 1st appearance of Carol Danvers isn’t already a major key, it will be after she transcends comics and becomes a cultural icon/household name next year after her movie and Avengers 4 hits screens. Mar Vell is now a minor character who will stay dead in the Marvel Universe, whereas Carol Danvers is about to become a flagship character of the MCU and adorn little girls’ lunchboxes and backpacks across the world.

Wow. A 9.4 from a $150 purchase. Worth thousands now. That's a nice return on value.

Since Carol Danvers will be the star of the next MCU movie...

I think Carol Danvers is a special case here as she was only a supporting character at the time, so obviously couldn't be on the cover. The name Captain Marvel is on the cover though, and the cover also reflects the story that she is in, unlike Strange Tales 110.. People point to Ms Marvel #1 as being more important as it's her first cover appearance and first time with powers, but like Tony Stark and Steve Rogers in the movies, it's Carol Danvers who will be important, not the hero identity. That's why MSH #13 is the book to have in regards to Carol, IMO.
