I've always wondered if you made a master of a coin (metal) then made an H1/H2 if the metallic properties would still be seen?
If so how does that work? If I make say a blue master where is the metal color stored?

Are you asking where the sheen went? By "metallic properties", do you mean the specular sheen?
The specular sheen is due to (partial) specular reflection from the metal. This sheen tends to desaturate the colour rendition, so that the spectrum effectively widens at certain angles. Also, the tonal quality widens. In a music analogy, the sheen is white noise superimposed onto whatever music you're listening to. In holography, this desaturation effectively translates to a wider bandwidth. When you shoot metal, you've got a hologram whose bandwidth is fairly angle dependent. This relationship is encoded in the Bragg planes.
