A swan hallmark with a "T" in the middle typically indicates that the item is made of silver and is part of the British hallmarking system. The swan represents the city of Birmingham, while the "T" denotes the year of assay, which helps identify when the item was tested for purity. This marking is an important factor for collectors and buyers to determine the authenticity and quality of silver items.
