Greenkat, I've had no trouble selling Forged Birth Certificates at 100 mil, neither has thehippi. You'd be shortchanging yourself to price it at less than half of that without even trying to sell at the going rate. If you want to go lower, try 75 mil and see if it sells in a week or so. If not, try 70 mil. I've only sold one at 75 mil, and that was to a friend. Obviously, it's your item and you can sell for what you choose, and maybe give a friend a SUPER deal if you want. XD
I've also quickly sold Gold Stardust Urns at 30 mil, and Cosmic Salve at 25 mil. (Just to give you a range there.)
