Engineered and precision 3D-printed in the UK, the Gold Sovereign Tester Tool Card is designed to quickly verify the diameter, thickness, and weight specifications of genuine British gold sovereign coins. Manufactured from a high-grade, low-tolerance polymer, it provides a fast and reliable first-line physical authentication check for collectors, investors, and coin dealers. Suitable for Full, Half, and Quarter Sovereigns, the compact keyring pocket tester is lightweight, durable, and easy to carry wherever you buy, sell, or inspect coins.
