Whether you buy a single coin or a bag of coins, you might come across bag damage. Like striking errors, bag damage can range in severity from slight to major. Even though some of them are harder to spot, they will affect the mint state of the coin or the coin grade. Bag damage is referred to as bag marks, but the results are the same. As damage goes, bag damage or bag marks are more common than other damaged coins.
Bag Marks or Bag Damage Examples
When you buy silver bags or a bag of coins, it is always a good idea to see if you can spot any damage on the coins. All coins are not immune to bag marks, and they are one of the most difficult things to prevent. When you spot damage, do not discard it.
Causes of Bag Marks
- Minting Process: During minting, coins are struck and then ejected into bins or bags. The impact and friction between coins can cause marks.
- Transportation: Coins are often transported in large quantities, usually in bags or containers. The movement during transport can cause coins to rub against each other, leading to abrasions.
- Handling: Human handling during sorting, counting, and packaging can also contribute to the presence of bag marks.
Identification and Assessment
Visual Inspection: A close visual inspection can reveal bag marks, often with a magnifying glass or microscope. Collectors look for the quantity, location, and severity of these marks.
Grading Standards: Professional coin grading services use standardized criteria to evaluate the impact of bag marks on a coin’s grade. Coins with fewer and lighter marks will receive higher grades.
Mitigation and Care
- Proper Handling: Minimizing handling and using protective gloves can reduce the risk of adding new marks.
- Storage: Storing coins in individual holders or cases can prevent further contact and reduce the likelihood of new bag marks.
Bag marks are a common and often unavoidable aspect of coin collecting, especially for older coins that have been in circulation or stored in bulk. Understanding their causes, impact on value, and methods for identification can help collectors make informed decisions when buying or selling coins.
