I am strongly tempted to say that you are having fun with us.
Grounded appliance (three prong) have the chassis attached to the ground.
If your ground at the breaker box was broken, and the ground wires were
shorted to a hot, you could get a voltage off the chassis. This would
require urgent attention.
But you would not get a reading off the chassis of ungrounded appliance (two
prong) because they are not attached to anything.

Either explain the problem in more detail, or go away.
