Does anyone have an estimation of prices on Bazaar?

Like, what the appropriate price for weapons and Magatama.

I have a level 8 required Grade 40 Staff, the 'Thirty Six Poets', and I put it up for 12 coins.

But then I saw a level 33 required sword for only 15 coins. Should I reduce my price, or is mine appropriate?

It's strange how much some prices can differ on here, and frankly, I have no clue what the best price range is for things.

Just about everything, unless enhanced to a certain degree, or is a rare item with demand like a black glass marble is sold at it's minimum OC price.

Sadly, certain things don't even sell when at that price either.
