925 Sterling Silver Certified Slabbed and Graded by PCGS as PR69 DCAM. The reverse depicts a portrait of Prince Philip and the obverse has the stunning portrait of Her Majesty Queen Elizabeth II by Ian Rank Broadley. Piedforts are coins which have been specially struck on thicker than normal blanks.As their name suggests they are closely associated with France, where from the twelfth century they were apparently issued by the Kings as presentation pieces. In Britain the practice of striking piedforts is later and less frequent, but medieval and Tudor examples are known. These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks. Why is a Certified coin a better investment? PCGS & NGC are the main two impartial Numismatic Grading Services in the world and is a guarantee that the coin is genuine and has been graded accurately and professionally. The sonically sealed solid plastic slabb is individually numbered so that the details of the coin(s) can be verified on a central database, and is also tamperproof.
