Just a heads up, I purchased this game in June 2013, and this achievement now appears to be glitched and unobtainable. I contacted the most recent person on TA to get this achievement (March 2013) and he said it unlocked normally, so it must be a recent glitch. Neither erasing my data or reinstalling the game fixed it. I wasn't able to get the gold transferred to my Fable III game, either, but that's not relevant to the achievement.
I contacted the game developer about a potential fix, and was told they no longer support this game. They suggested I contact the publisher, Microsoft Studios, but I wasn't able to get any help from them, either. I thought I'd post this info for any completionists who were considering buying this game.
UPDATE: CL1333 got a reply from Xbox Support on Twitter that this feature has been "permanently retired," making the achievement unobtainable.
