This note adds six new cardboard advertising tokens and an unprinted blank to the 16 previously published. The card tokens are in the Royal Mint Museum collection. Background notes are presented for all of the pieces. The final card penny is shown to be a self-advertisement for the novelty advertising company of D. Harper & Co. of Holloway Road, London. Contemporary adverts confirm that this company was a manufacturer of card advertising pennies with images of the monarch on one side.
