Hi,
From my point of view as someone who does not collect pristine coins but prefers circulated coins with age and history shown on the coin
Warts and all is best to me but not too badly worn, I like to see the detail of a coins design
....Chop marks are a plus and Counterstamps are nice to have. Love tokens are Ok too.
To me they add an extra dimension to the coin but I fully understand someone who prefers UNC coins would consider it as damage or defacement.
