Time to change the locks.

"Face" it, she has too much "time" on her "hands."

Whether it's your mom or not you should report her to the cops. Breaking and entering, theft of private property, selling stolen property. And the person who bought the collection- recieving stolen property. So you can get your collection back.

I think it’s time to possibly become estranged from your mother. I have a full blooded Sister I haven’t seen in literally 40 years. And I’m all right. I don’t miss her. I don’t know if she’s even alive anymore. So if she breaks into your home again or anything else like that you don’t like she goes to Jail. She goes directly to jail. She doesn’t pass Go! And doesn’t collect $200. There’s an old saying that’s asks are you better off in your life with her or without her. Only you can answer that.

Call the cops, report it as stolen property, and use her admitting to selling is to have her charged for the theft, then just change your locks. curb her ass.
