From my experience cleaned coins don't sell, most are purchased for the gold content but if the coin is high grade AU or uncirculated I consider how it was cleaned and how much damage has been done. You will not get full market value for the coin, rule of thumb is subtract 50% of the value or more on cleaned coins. So if your coin is uncirculated the date 1915 is common and the value is $290.00-50%= $145.00 and the melt value as of today is $139.45 that is the value of the coin
Artificially. Five.
The collector value of any coin will be lost if it is cleaned with anything. Any acid or other abrasive cleaning agent will destroy the finish of the coin and remove minute particles of the metal. If the coin has no collector value to begin with, you will end up with a lovely shiny coin.
