From the mid-70’s; most likely a TV movie, i.e. ABC Movie of the Week or NBC Sunday Mystery Movie episode of MacMillan & Wife, Columbo, etc.
The scene I recall is in a large room in a mansion(?). The room is filled with racks of comic books as well as a large paper shredder. The protagonist(s) are fighting with a group of criminals or gangsters in order to keep one particular comic book from being shredded. One of the gangsters has an old-style artificial claw hand and gets his false hand stuck in the paper shredder during the altercation; sparks fly.
