Price suggestions are based on completed sales.

If you sold this item for 230 keys, then your price suggestion would have to be 230 keys. Not a range like you have here.

In addition, you must include every completed sale within the last 2 months (if there are any others).

You must include evidence of all of these sales (as well as your own) through backpack comparisons or screenshots, for example.
