9705.31.00.10 - Gold

This HTS category, 9705.31.00.10, specifically classifies gold items that are considered collectors' pieces of numismatic interest and are 250 years of age or older. Numismatic interest generally pertains to coins, medals, and other metallic currency or tokens. Therefore, this heading would encompass historical gold coins, solid gold medals, or other gold objects that have acquired value and significance beyond their intrinsic metallic worth due to their age, rarity, historical context, or artistic merit, and meet the 250-year age threshold.

This classification is distinguished from its sibling category, 9705.31.00.40 ("Other"), which covers gold items of numismatic interest that are less than 250 years old. The critical distinguishing factor is the age requirement; this heading exclusively pertains to gold numismatic items exceeding the 250-year mark.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification hinges on the precise characteristics of the gold item: its numismatic significance, its composition primarily of gold, and its age exceeding 250 years. Classification decisions will rely on thorough documentation and authentication of the item's historical provenance and numismatic value.
