Shield?

It’s a piece of jewelry, like a broach or something

Saw some videos that mention it's just a collectible and not part of anything

I'm not talking about what you loot off her body before the house burns down before you go upstairs there's a gold shield with the Braithwaite Crest on it it's sitting on top of the fireplace but when you take it to a fence or anywhere it sells for 0 dollars
