Watch List notes:

Fifty Pence, The London 2012 50p Gold Proof Piedfort Olympic Gold Medal Winners Set, a spectacular 11 coin set featuring the 11 sports that Team GB won their 29 medals in. Proof FDC with certificate number 2 (NO. 02 embossed in gold on the wooden lid) housed in a quality cabinet style wooden presentation box with a separate draw for the certificate and CD (unopened), and a CHIEF ENGRAVER MASTER PROOFS presentation card which shows the engraver's master proofs embossed in gold, the whole with outer card box. This is a rare set and must be The Holy Grail certainly of 50p sets and perhaps of the entire Royal Mint modern series since 1979. Some ambiguity has surrounded the mintages of these coins as the first time they appeared in The Coins of England reference book by Spink it was stated that just two of each coin had been struck one for the designer the other for the gold medallist. Here at London Coins we have offered four individual coins since 2012 all different sports (athletics, cycling, triathalon and tennis). The certificate on this set states 2/29, however the vendor has provided us with actual sales figures (rather than mintage limits) that he has obtained from The Royal Mint which indicate that just 15 of these 11 coin sets exist and states the additional coins issued separately so giving the following total mintages for each sport as Athletics 26, Boxing 18, Rowing 26, Cycling 26, Equestrian 22, Sailing 17, Shooting 17, Tennis 25, Taekwondo 15, Traithalon 22, Canoeing 17 (therefore no Taekwondo coins exist other than in these 15 sets). These are excessively low figures and anyone with an eye to wealth creation should reflect on the current values of Royal Mint proof sets that include gold from yesteryear, sets with mintages of 150 (10 times more than these 50p sets) can realise six figure sums. As far as we could tell this is the first example of this set offered so preparing an estimate can not be done on past results, what we can say is that the 4 individual coins we have sold totalled £20,800 or over £5,000 per coin.

Estimate: 35000-55000 GBP
