Hi my name is Ryan, I recently have become more interested in the coin hunting and somewhat collecting .
Just trying to find out how to approach looking beyond the dirty look on some older coins I have come across?
Also just hoping to meet some like minded people who may be interested in sharing some advise and recommendations in regards to coin hunting and collecting .

Just wondering if anyone knows what would cause a rainbow patina/tenting to a Jefferson nickel from the 1940s? I have been noticing that type of discoloration on a few coins I have come across; it is something I have not really scene . |

One of the best ways of getting a rainbow toning on an MS grade coin is to place it on a piece of white (chlorinated) paper, and leave it in the sun on a window sill for a few weeks. Remove, when you think it is done to your satisfaction and judgement. Works a treat!  It is for this reason, that I never pay any extra for an attractively rainbow toned coin. It IS in fact, a form of deliberate post mint damage. The only way to fix this problem, is to let the coin continue the toning to an even, gun metal gray. That is why blast white MS silver coins are rarer. Edited by sel_69l

Because of their unique composition, nickels tend to tone more subtly than silver coins. I recently picked up this 1941 proof which shows hints of rainbow toning.  |

But blast white aren't rarer, they just dip them to remove whatever toning that's occurred, coin dealers do it all the time to improve the eye appeal of badly toned coins.
I'm OK with toning on older coins 10-20-50-100 years old. It's the rainbows from 2016 or even this year that I know can't be naturally possible. It takes time to get there and pretty obvious if not enough time has passed that the coin was artificially toned.
Some people like that though, I won't knock them if they like a 2019 rainbow silver American Eagle, just not something I would buy into.

Welcome to CCF...depending how your nickel was stored and what exposure to the elements it had could explain any toning. Many older coin envelopes contained sulfur and this when in contact with coins over ime could give them a nice tone. Many people have realized that buyers will pay a premium for a toned coin so they artificially 9heat/chems) tone coins.

It may have been stored prior to the jar in a place where it was exposed to some environmental issue, then it went into the jar...some of the other coins in the jar may have had substances that off gassed and affected your nickel...a lot of possibilities.
