What does it mean when it refers to "bag marks" on a coin?
Is there some way to repair them?


"Bag marks" are damage to the coin,usually causd by the coins rubbing or banging against each other while loose in a bag.

Anything you attempt to do to repair or hide this is only going to increase the damaged,and reduce the collector or numismatic value of the coins.

Such "repair" work is considered an alteration of the coin, a "doctored" coin.


  1. Hi Dickson,
    We noticed many PATA commemorative RM1 coins have quite a number of bag marks esp in between the $1 figure on their reverse.
    Cheers :)

  2. Dear whycollect,
    Marks in between the $1 figure on PATA reverse were the stacking marks.Because of the esp.high reliefed of the obverse details,when we stacked them,it scratches the reverse of the next coin.
    A lot of our Queen E,50 Cents exhibited the same problems on the obverse of the coin.esp- on the cheeks of the effigy.

  3. Hi Dickson,
    Ya, been wondering why so many bag marks on some of these coins.
    Thanks a lot for the information, Dickson :)
