Most Third Party Gading Services would only certify the coins as Genuine and give it a Details Grade with notes (Attributions) such as "Damaged" and/or "Improperly Cleaned" or other notes. Sometimes this type of Grade and notes (Attributions) can do more harm than good for the value of a coin. If all you looking for such as in the case of a really Rare coin, then these are always wanted and acceptable but for non-rare and lesser valued coins, they are very dentimental.
