Default Card altering...what is happening in the coin market.
Posted By: barrysloate

It's very hard to clean a coin without some expert being able to detect it. It causes either an unnatural patina or in some cases causes surface striations that can be seen under magnification. If a grader misses that a coin has been cleaned he certainly goofed.
