Maybe, I probably wouldn't try to claim on the insurance though. My most expensive to replace thing is probably my cd collection, which as far as I'm aware thieves don't go for, my tv is small cheap and unbranded, my laptop is ancient and the battery is knackered. I suspect the most fence-able possession I've got is a Kitchenaid mixer.
The only reason I even have contents insurance is because it comes with the buildings insurance.
