Marketboard Prices

I was wondering what the average prices are because I see people laughing at others for buying overpriced items. But how should you know how much it's normally worth? Basically just hit the check mark? Copper ingot aren't worth 23 emeralds I believe

 

With most items, you just gotta learn their value. Some items go up and down in price a lot (eg mythical) and the automatic prices the trade market tries to sell them for is often way off, depending on their identifications.

 

I wish it was like Final Fantasy 14 marketboard, where you could see the past transactions. Still thank you. I will still wait for other answers though ^^

 

Pretty sure Wynntils (a mod) can show those prices but it's dangerous to use wynntils because sometimes there are false banwaves which wrongly detect wynntils as a hacked client
