How are scrolled/potentialed items priced?

I ask this because I have quite a few things I want to eventually sell but I have zero clue on how to price them and I feel annoying asking for a price check every time.

Using the FM as a reference barely helps me because it never really has any item similar to what I want to sell and I'm an FM noob anyway. :\ But to those who do use it for price referencing, how do you do it?

I could list the items I want to sell for a price check but that's better left for the Price Check section.

For scrolled items you can use MTS to get a rough idea of price in K NX, then multiply by 15 or whatever to get Mega-meso price.

For really godly stuff, price at max mesos and ask for offers. As a buyer I find this annoying, but what else can you do?

Also start prices way high and lower a bit each day if it doesn't sell.

It's difficult to give an idea for prices of potentialed items, since it depends on server, level, whether the item is common class or class-specific, whether it is a popular item, and of course which stat is present. In the past 15% stuff was usually way over 1 billion, 9% stuff 600M or so, 6% 300M?, but I think prices are dropping, and I'm not a FM hor either.
And, yeah, 3-line is worth anywhere from 2x to 10x what 2-line is.
You should be able to find enough similar potentialed items in your FM to get a rough idea.

TL/DR: It's worth what someone is willing to pay. So start high and lower a bit each day.

List the items in the price check area. I will help you out.

These prices are for clean armor helms,overalls,etc. If you have scrolled ones best to ask for price check

(2 line) 6%(epic) stats and clean will sell for 200m.
(2 line) 9%(epic) will sell for 350m
(3 line) 15%(unique) sell for 1.2b
(3 line) 18%(unique) sell for 1.5b

Cant give you a weapon price range cause its based on how well its scrolled.

From what I've seen (not counting potential) scrolled items are worth the value of the scroll(s) passed + the value of the clean item + around 5-20+ or so mill added on depending on how hard it is to scroll said item.
If you want the price of things you're selling just look around for similar items and gauge your price based on that.
