Silver bullion does not require a hallmark. Hallmarking is a process of verifying the purity of precious metals, such as gold and silver, by stamping them with an official mark. This mark indicates that the item has been tested and meets the standards set by the government or other regulating bodies. Often jewelry and antiques will be stamped with such a hallmark.
Hallmarking is not required for silver bullion, such as precious metal coins or bars, though it is common to find the silver purity and weight inscribed on such products. The government or mint issuing the bullion generally guarantees its precious metal content.
