“If you run the scanner over this one, it would probably come up as a bottle cap,” said Bob to his detectorist pal Mike. It was very nice to chat with these fellows after drawing them on my pocket sketchbook.

Bob said he once found an old Spanish silver coin with the face of king Alfonso XII at low tide under the ferry dock.
