And before I go, you really shouldn't be using this to prop open your building's door. This is an antique fire brick, I'd say pre-civil war. And note the uneven orange hue and the embossment on the back. Quite a nifty little piece of Americana, you could get fifty, sixty bucks for it from the right collector.
I watch a lot of Antiques Roadshow.
