2005 & 2006 Gold Proof Half Sovereigns - Boxed & COA

A 2005 and 2006 gold proof half sovereign are coins that were issued in the UK and are made of 22-carat gold. The proof refers to a method of coin production where the coins are struck multiple times to create a high-quality, detailed, and mirror-like finish.

The fact that they are boxed and come with a COA (Certificate of Authenticity) indicates that they are special collectible editions.
