Are you referring to the 'mirror' and 'matte' 1c coins from the 1960s in the pliofilm proof-like sets? Could what you are seeing be the sets with lacquered 1c coins? I wrote an article on this, in the CN Journal a few years ago.

No - it has a layer of lacquer, applied to the coin after the strike. It is a common Proof-like strike, some sets were lacquered, and some were not.

I tried to help by posting the definition of 'hologram' but the word is NOT IN my 2006 Webster's Dictionary. There is nothing between 'holocaust' and 'holstein'. I might need a newer dictionary. ?

I'm sorry, Rocky, but I still don't see anything that has to do with silver, plastic or holograms. All I see are what has been suggested by others on here. What I think you are seeing are proof-like finishes vs matte finishes and lacquer coating on some of them, sometimes with very excessive lighting and magnification. I know you search hard to try to find new, unknown varieties or errors, but other folks here just don't see things the way that you envision.

rocky,
For sure the lines you are seeing on your coins is not holograms.
Hologram is an optical feature based on micro grooves to diffract light. The line pitch is in the orders of microns.
Modern banknotes have holograms as security features.
Some Proof Mint Coins have holograms.
In your coins, I guess the parallel lines are more a die polishing signature.
