 Not a normal oxidation color for a nickel - probably just some crud that would come off with acetone.  to the CCF! Edited by Coinfrog

So I google the PVC and does it mean these things are what caused my coin to turn green?  |

Yes...some of those old albums have plastic pages that are loaded with PVC.
Check some of the other coins closely for signs of residue. Smell the pages. Does it smell "plastic" or kinda funny? Do the pages feel oily?

I've gotten green crud like that off of copper coins with soap and water. Might try that.

As a general rule,never clean coins. If you damage them with cleaning you can lose 20%-70% of any potential value. Acetone will not harm a metal coin. John1 |

Thanks everybody I will try the acetone and I'm still searching for something better to store my coins. It's hard to distinguish between all the online stores. Any suggestions for a good site.

There are quite a few inorganic an some complex organic corrosion salts of both copper and nickel.
What is needed to produce what you see here is chlorine in a complex organic form, and moisture. Soft PVC album pages in a humid environment would be a typical way to produce the sort of result that is pictured.
I agree: give it a rub between the fingers with good old soap 'n water, then rinse in acetone, to remove the organics of soap residue and skin oils.
