Cornish penny

My husband J. was sorting through an old collection of coins today, while we were watching Wimbledon!
I thought this to be the most interesting - it is self-explanatory really - he has had it for so long, and can't remember how he came to have it!
Family staying for the weekend, and an early birthday dinner for J tonight while they are here.
And a bottle of something delicious cooling in the fridge!
