I started stacking in 2011 and i bought a 1/2 sovereign from the Royal Mint and i almost had a nervous breakdown at paying so much for a coin, cost me £155 and it was my first gold coin but it started me on a journey so i like your 2011 proof, very nice. The best thing about starting out as a stacker in 2011 is the coins have got a touch cheaper to buy over the years but i wish i had started pre 2008.
