I don’t think there’s a law that’s stopping you. It’s just the question that will a pawn shop want it? And also are you interested in making a profit or do you just need to dump some swords anywhere?

Unless you buy them extremely cheap, there’s no way a pawn shop will give you a higher price - especially if you order multiple items (or even worse, in bulk).

If you’re looking to make a buck, I would take those things to a bigger LARP event and sell them directly to the clients for a margin.

Alternatively offering these to weapon stores or comic book stores might also get a foot in on the door.

Not a business idea, more of a scheme of a brighter sort.

You rob a liqueur store for a pallet of vodka, sell the vodka for half the price and then buy vodka for the profits to get drunk!
