As we're approaching the bedding down for the winter digging sessions, I thought I'd ask what the most unusual or interesting things are that everyone's found on their plot.
Two years back we turned up a 1699 William II halfpenny. I think that our plots were part of the grounds of a grand house (Bury Lodge) at that time, but haven't been able to find proof.
(Oz has to swear he was compos mentis when he found his contribution!)
