Extremely BU examples already take on a bluish hue so yes, they are not rare by any means, I would however be wary of neon blues.

 

I have 3 in some soft plasticy + cardboard holder that have all taken the hue. I was wondering if it was inherent to the steel or to the platic in the holder. Not neon but iceberg/glacier blue. Really cool color.

It is actually a property of the zinc. When new with no oxidation zinc is silver in color. When a heavy oxidation layer develops it is white and/or powdery. But when it has just a hint of oxidation on the surfaces it takes on a faint bluish silver white color. Ice blue would be a good description.

I would be worried about PVC

 

Ill try and take a pic to show the holder. Its some kind of mint or other place's souvenir type of holder with a carcboard section printed with info about the reason for the coins and then 3 little windows of some kind of plastic that shows the coins. I dont think my current camera equipment will do much to grag the blue hue but maybe a picture of the holder will confirm if this type of storage medium is known for the color.

 

Nice coin ENC, looks flawless.
