Whoever paid $14,550 for a 9.8 is a fool. They will never see that money back. I suspect they jumped on the character bandwagon and thought they would get in early. Investing based on possible appearances is high risk with no guarantee of return. This is especially true when considering that issues featuring characters that have (eg. Falcon) or will (Ms. Marvel, but looking more tenuous) appear in the MCU are not holding value.
Even Werewolf By Night, the host title for Moon Knight, commands little attention. The 1st issue and Marvel Spotlight #2 can still be purchased for a moderate price.
I believe the best investment was, is, and always will be the Silver Age. For $14,550 I can have several key SA issues.
