100BC, cool!!
I know what you're saying about wasting money, but if it means something to you, then its worth it (not $41k though, but depends how rich you are).
For me it probably would be computer games... Buying a brand new game and then taking it home, the best part was always taking the wrapper off and putting it in for the first time... One of my most significant memories is playing Fifa 94 on the snes for the first time... and to own the game still sealed would take you back to that moment of anticipation...
