As somebody who has been playing since the beginning and was around during the original Regalia promo, I'm certain that the old items NEVER went for under 100k, even when they first came out. It's not so much greed as "this person had to spend $10 to get theirs in game, they're going to want their money's worth of in-game money." $10 can buy me food for three days.

It sucks saving up sometimes but instant gratification gets boring. These new ones are actually a lot cheaper than the old ones ever were, especially the Tabards. (Except maybe Moonstone.)
