What is a Chrome Winchester Cannon with Tires worth?

Oh, dude, a Chrome Winchester Cannon with Tires is worth about as much as a unicorn with a jetpack - it's a rare and unique item that's hard to put a price on. But if you really want a number, I'd say it's probably worth enough to buy a small island or maybe a lifetime supply of avocado toast. Like, who even has one of those lying around to sell anyway?
