A Clyde Navigation Token was found by Andy Coyne, a contractor's operative, during renovation works on the Albert Bridge in Glasgow. The token was found during the removal of the existing parapet; it was lodged between the parapet and the masonry plinth at the north east corner of the bridge, and was embedded in a layer of dirt that had accumulated in the gap between the parapet and the stonework. It is unclear whether it had been placed there at the time of construction or dropped in some time later. There is a long tradition of items being placed in the foundations of buildings to ensure good luck, and this token could perhaps represent a continuation of this. The Albert Bridge was constructed between 1868 and 1871.
