WIW NOS 2863349 air filter element

[challenger3406pk]

So I have a few NOS air filter elements. Pretty sure they were made late 70s or early 80s based on the other parts I got with them. I know this is the number on the service decal on air cleaner assemblies for the dealer. They are black and have diamond shape on the outside screen Any ideas on value? Pretty cool display piece as well!
