What is the oldest thing in your home?Watch this thread
Well our house is 135 years old to start with. I have some books from before then, going back as far as the 17th century - my oldest book, I think, is a copy of the Authorised Bible, "newly" translated from the original tongues &c.
I have some tools that are a few hundred years old too - the oldest of these is a mesolithic hand-axe, possibly 10ky old.
Probably the oldest thing in the house (and which I own) though would be a fossilized echinoid I was given as a child, which according to the certificate that came with it is from the middle Jurassic.
