Believe it or not, 18 months have already passed since the debut of Moon Knight on Disney+ back in late March of 2022. More than half a year later, let’s take a look and see if Moon Knight’s key issues have held -- or lost -- much of their value.

Moon Knight has come and gone on Disney+. It received mostly positive reviews from critics (86%) and audiences (89%), and most praised Oscar Isaac's multi-faceted performance. Its CGI was also strong, from Khonshu, the ancient Egyptian god of the Moon, to Moon Knight's elaborate mummy-like costume. We haven't seen Moon Knight since the show, but we hear he'll be back to battle Rama-Tut in Avengers: The Kang Dynasty. With the market having forgotten about Moon Knight, could it be a good time to buy?

Werewolf by Night #32 has lost over 66% of its value since it reached its all-time high sale in December 2021.

This is THE key issue for Moon Knight and one of the most significant key issues of the Bronze Age. In my mind, in terms of importance, it's right after Hulk #181, Amazing Spider-Man #129, Giant-Size X-Men #1, and maybe Marvel Spotlight #5.

When you review this issue's sales data over time in its most common grade on the CGC Census (an 8.5), it's clear this book has taken a massive beating ever since the end of the "comic boom."

As you can see in the screenshot above from GoCollect, after reaching an all-time high of $5,499.50 in December 2021, just a few months before the debut of the TV show, the value of an 8.5 has absolutely plummeted. Today, according to GoCollect, the FMV of an 8.5 is $2,200.

One copy sold for a mere $1,651 during a recent auction on eBay on August 23rd. Purchasing it for that amount is like going back in time four years and buying it in early 2019 before the show had even been announced. In my opinion, that price is a steal for a major Bronze Age key in high grade.

Since late 2019, a 9.6 copy of Moon Knight #1 has produced roughly a 40% ROI over four years.

Moon Knight #1 is also a major key issue for Moon Knight for a few reasons: (1) this is the first issue in his first ongoing series; (2) it contains the story of Moon Knight's origin; and (3) it contains the first appearances of two characters: Khonshu and the Bushman. CGC doesn't even include the first appearance of Khonshu on its label, but it probably should going forward.

During the comic boom, a 9.6 copy of this issue (the most common grade on the CGC Census) exploded in value, reaching an all-time high of $327 in September of 2022. Then a major correction occurred affecting the entire comic book market, including this issue. Today, according to GoCollect, the FMV of a 9.6 is $140. Still, if you look at sales data in late 2019 before the pandemic and the comic boom, a 9.6 sold for just over $100. That's roughly a 40% return over four years, an ROI primarily driven by the MCU.

Considering that we will likely see Oscar Isaac, Moon Knight, and Khonshu again, it might not be a bad time to pick up some of these key issues.
