~180K, a bit less for certain pieces (like accessories ~120K).
More people selling means more competition, makes the market better for buyers EXCEPT for super rare/luxury items. As a legacy server we have a lot of people with massive piles of Scrooge McDuck gil, so when something gets to be priced at that unknown value or at the "this is super rare to obtain" then prices can be many million no problem, like houses being sold for three to four times their NPC cost. (Thankfully for buyers there is some competition and desire for the ironwork sets, and perhaps the crafters selling them are not too evil haha).
The ornate ironwork versions are usually 3 million + though.
