Nearly all badges from the Danbury Mint collection were anodised with two blades and made by Firmin.
However, a few were in metal: Blues and Royals (bronzed), QDG (chrome) and RAChD (blackened).
Badges from the second (post Options for Change) set were likely made in ‘new metal’ to emulate the official issues.
