Martin Allen (pers. comms.) noted: "this is an excellent example of Series L (Type 23e). Other specimens have been found in the Thames at Lambeth and at Tilbury, and this discovery adds further weight to the notion that these coins may have been minted in London, although they are also found elsewhere in England."
Estimate: £600 - £500
