If the hole in an ancient coin is naturally formed, such as corrosion or other natural processes, then the hole may not significantly affect its value. However, if this hole is man-made, for example, it is used to embed jewelry or other decorations, then its value may be greatly reduced.
In some cases, even if there are holes in ancient coins, they may still be valuable for collection. For example, some ancient silver coins may have holes, but these holes are caused by mistakes in the manufacturing process or other reasons. These ancient coins may still have certain collection value, especially for collectors who are interested in the history and manufacturing technology of ancient coins.
Generally speaking, if there is a hole in an ancient coin, its value will be affected, but the specific degree of influence depends on many factors, such as the cause of the hole, the age of the ancient coin, the manufacturing materials, the preservation state and so on. Therefore, it is suggested that when buying ancient coins, we should pay attention to the identification of authenticity and understand the influencing factors of ancient coins.
