A vintage leather wallet typically refers to a wallet that is inspired by styles from a previous era or is an actual piece that's at least 20 to 30 years old. Genuine vintage leather often shows signs of wear and natural aging, such as a patina or minor scuffs, which add to its character. The craftsmanship, design, and quality of materials are often superior to contemporary pieces. Authenticating a vintage leather wallet may require examining the stitching, hardware, brand markings, and sometimes even seeking professional authentication.
