Looking for opinions on this Barber Quarter 1913 I picked up. Any one can tell me the present Grey Sheet on this? Thanks.
The Greysheet does not list prices for cleaned coins. I'm afraid the only way to determine value for a cleaned coin, or any problem coin, is to sell it.
There is no rule of thumb Carter for it can depend on too many variables - the availability of the coin in question, the severity of the cleaning & resulting damage, and most of all - how badly the person wanting to buy the coin wants it.
