You can't trade items of different qualities. All of them must be the same quality: 9 commons or 9 classy, or 9 Spiffy, etc...

After trading them, you are guaranteed to recieve an item of at least one higher quality (For example, you trade 9 common items and get something Classy) but you can also get qualities even higher. (For example, 9 commons for 1 Spiffy), but no way is it going to below or the same quality as items you've traded.
