Heya safiya - have you seen
the Marketplace yet? You can get price info there easily by searching for the item you want to sell. Then you won't have to worry about whether folks are taking advantage of you or not. :)
Here's an MP link to the Phear Meh for you:

You'll see there's a price range there for recent sales, but since there aren't any being sold at the moment you could potentially ask for more than the average and get away with it. ;)
