York, England, 866-1067 AD. Forged iron, of classic early “fiddle key” form. Just over 1 3/4” length and distinctly different from later nails which were flush with the shoe. These, used with the “pie crust” edge shoes projected below the shoe, and the horse walked on the nails, not the shoe. The head was forged to a low domed form. Much more rare than the shoes.
