As we all know, MCU shows on Disney+ has served as a catalyst for the comic book collecting community. Loki will be no different, and neither will Loki keys. Below are the shakers and, more importantly, the sleepers as they relate to Loki as I see them.

Shaker: Fantastic Four #353, 1st appearance of Mobius M. Mobius

Fantastic Four #353 is the biggest shaker. Just in the past year, CGC 9.8 copies of this book have exploded in value rising by an astounding 241% during the past year. Less than two months ago, a 9.8 sold for $515 on eBay.

You can still buy high-grade raw copies, however, for $50 or less on eBay. Personally, I wouldn't recommend buying this book since we've all known that Owen Wilson will play Mobius M. Mobius for some time now, and this book has likely reached its ceiling because I don't think it's likely that Mobius will play a major role after Loki concludes. I'd sell it now if I owned a copy.

Sleeper: Avengers West Coast #62, 1st Full Appearance of the Time-Keepers

We all know the Time-Keepers will play a role in Loki; in fact, we've seen statues of the Time-Keepers in the show's trailers. Even so, strangely, collectors are sleeping on their first appearance in Avengers West Coast #62.

Remarkably, according to the CGC Census, there are NO graded copies of this comic, and, accordingly, no sales data on GoCollect. Reviewing sales of raw copies on eBay, high-grade raw copies are selling for around $30 or less. About four months ago, similar copies were selling for around $20, so the FMV for this issue is starting to creep up. If the Time-Keepers do appear in Loki, this one is poised to go through the proverbial roof.

Shaker: Thor #617, 1st Appearance of Kid Loki

The second biggest shaker is Thor #617, the first appearance of Kid Loki. Just in the past year, CGC 9.8 copies of this book have exploded in value rising by over 76% during the past year. Less than two months ago, a 9.8 sold for $515 on eBay. You can still buy high-grade raw copies, however, for $75 or less on eBay depending upon the grade. Unlike Fantastic Four #353, Thor #617 may not have reached its ceiling since there's a good chance Kid Loki may reappear in an upcoming Young Avengers TV show or movie.

Sleeper: Thor #245, 1st Appearance of He Who Remains

Collectors are also sleeping on Thor #245, the first appearance of He Who Remains, in my opinion. He Who Remains is an obscure character for sure, but he's significant because he created the Time-Keepers.

Even though this is a Bronze Age book, according to the CGC Census, there are only 42 graded copies of this book in existence and almost no sales data on GoCollect. Looking at sales of raw copies on eBay, raw copies are selling for $5 to $10. This is insanely cheap for a Bronze Age book with a first appearance with high speculative value. If He Who Remains does appear in Loki, I could see raw copies selling for $20 to $30 or a 400% increase in FMV.
