Love this topic and replies.

Personal object which is oldest is probably my old threadbare Teddy bear who was a cousin’s before mine and must be around 60 years old.

Joint oldest object is the sole from a Roman sandal- not sure how old but at least over 1,500 years which sounds weird writing it out. Lots of Roman digs locally and so things like these aren’t too uncommon. Husband was given this by a friend working on a dig in the 80s I think, stuff like this was preserved by the mud.
