ours is about $45 000, we got the renewal for it today! Lol. Ours was a guesstimate, but we did get my engagement ring added, so that's insured for theft/loss for about $2000. Good thing if it falls down a drain! We didn't have to provide proof of anything, just gave them the specifics for the ring and it was all done over the phone (we're with AAMI). We spoke to them about insuring our tv as we got a large LCD tv a few months ago, they said not to bother as if the house does go up in flames, the assessors will just walk through and go yep that pile of plastic was a tv..and replace it new for old, so doesnt matter what the tv was to begin with.

We probably couldn't replace everything we have with $45g, but it's a good start if something does happen.
