1983-2014 AD. Obv: blank. Rev: blank. Edge: with incuse DECUS ET TUTAMEN inscription. See S. J1-J35 for types. 9.47 grams. From circulation. The method of manufacture for £1 coins by the Royal Mint was first to punch out the blank; the blank then passed through a machine that placed the inscription wording to the edge and finally, the edge-treated blank passed to the coin presses where dies stamped the obverse and reverse designs and the edge milling lines. This example clearly missed the last striking stage in the process. Several issues of the mono-metallic £1 carry this particular edge inscription, from 1983 through to the last currency issue in 2014.
