Easy answer. Those with the knowledge to understand what true doubling is. That's not something a person can learn without a lot of study.
tons to learn, like plating blisters, split plating, mechanical doubling, die deterioration doubling .. stuff like that which confuses newer collectors who are looking to cash it rich.

#1 don't touch coin with fingers #2 take clear photos. Make sure everyone is able to see the doubling.
