So the boy is back. Retired in October last year and sold up the house at Osborne and moved south to a nice place on the hill at Encounter Bay. Lovely view of the Bluff, Right Island, Seal Rock and Granite Island......all beside the point.
It's school holidays, so I took the ETP to the local high school for a swing. Among the expected $1 and $2 coins was a nice 82 on the conductivity meter, in hard clay under the sand of the volleyball court. About 2 inches down I popped up what I thought was a sixpence, but it was as black as toast.
So at home i gave it the treatment with some foil and spit, and out came an 1881 Adelaide Industrial Exhibition medallion. Fairly trashed with most of the Exhibition word now gone. Flip side is the Lords Prayer. Still a nice bit of silver for the collection.
