Hi We would like to clarify what actually happened, a client of ours Graded some of the 2012 Diamond Jubilee Silver Proof £5 plated in Gold and were submitted to PCGS for Grading and can confirm the coins and slabbs are genuine. PCGS labelled them as the Gold version incorrectly by mistake, the seller of the coins sold them to this person Michael Williams as the £5 Silver Proof Coins Plated in Gold versions as the seller sold them with the blue boxes and Royal Mint Certificates of Authenticity also showing them as Silver Gold versions and sold for from memory £600-£700 for all three coins with the seller not knowing what the buyer was up to and oblivious to the mistake PCGS had made. Once the buyer who new exactly what he was doing did the rounds to different dealers and once The London Coin Company were made aware of it we contacted PCGS to get them to remove the Cert Numbers to make sure it was brought to collectors attention. We as an official authorised dealer of PCGS in the UK and Europe only sell genuine PCGS Slabbed and Graded Coins and are the largest PCGS Dealer in the United Kingdon and possibly Europe. We hope we have clarified and cleared up a few things for contributors to this thread. With best wishes The London Coin Company
