I've never, in about 7 play-throughs of the early game, been able to pick up a gold piece in the bigger pyramid that seems to be under the chest with the good 1H sword in it. When I'm standing, I see the gold; but I can't pick it up, I find myself kneeling in front of the chest instead.
I realise 1 gold piece is totally unimportant, but it does kind of bug me that I'm being too stupid to get hold of it.
