Bashed Dead Center

Take a file and try to take a light pass on some part of the center that isn't used, like the back end of the tapered cone. If it just skates and doesn't cut then it is hardened. If it cuts readily, it is not hardened.
 
I am surprised that a group of enablers are not jumping on the obvious answer! Now in order to save your $20.00 dead center you absolutely need to have either a surface grinder and spin indexer, or you will need to find a tool post grinder.... But seriously, as mentioned just knock the hog nose off of it and you will be fine for all but the smallest diameter workpieces.
