My mums family were from Wallsend. Everyone in Wallsend used to dig up scraps of Roman pot, didn't think anything of it. My grandfather was lucky enough to find a small roman pot, intact except for the chip he took out with the spade, so he took it home, cleaned it and put it on the mantlepiece.
My mum, some time when she was a tiny sprog in the late '30s, managed to knock it off and break it.
So they threw it away
