case-by-case basis and lincolns are included in this as i've seen a ton of them with the same hue of blue. coincidence? perhaps.

One is what I call the Acetone effect, which is the removal of natural occurring oils on coins that are BN or RB. The result is something that looks like this:
Whatever solvent you use, MS70, acetone, laquer thinner, or whatever, the blueish tone is an unnatural look. It can be cured by reapplying some oil to the coin. So, it is not really a toning alteration, it is a stripped coin. Don't pay a premium for this type of toning, but don't condemn it either. Just understand that someone dipped it in solvent. BTW, that coin is junk! I grade it MS63BN.
That said, Proof Indian cents come with blue and magenta and emerald toning all the time. These came out in the 1930's when old hoards came to light. Check out the Eliasberg sale - it had some. It is long-term envelope toning. Sometimes debris of the ages covers the toning up and makes it brown, or slightly muted. Take away the debris and you find the old toning again. This is real toning, uncoverd by a solvent. Collectors pay strong premiums for it.
There may be instances where you have a combination of the two processes I mentioned, but neither process creates toning by using any solvent.
I wrote an in-depth article on this, and I'll be happy to post it tomorrow.

I understand what you are saying here but if I recall correctly it is what Elcontador has stated above. It's Proof INDIAN cents you should look out for when it comes to your quote. All else is case by case as stated.

despite Rick's expertise in this area I don't believe it to be as simple as he states. certainly there are some coins with toning like this which occur naturally but most are......................manipulated. also, I have never seen the use of acetone on any coin bring out color like this, usually it does nothing at all without the aid of a toothpick or cotton swab. on the other hand, let's consider MS70.

I searched before, because I remember seeing it in the past. Perhaps I used the wrong terms, cause I came up with zilch! I just saw a few blue toned IHCs and was curious about them in terms of legitimate toning or enhanced. They are not my area of expertise. I have considered assembling a "blue toned type set" and they came to mind.

I am so glad to see someone of Rick's calibre state this, as I feel the same way.
If some purists don't like it that's fine, if some services won't slab them (sometimes!), that's fine too.
But oftentimes, to me, they can look very attractive - much nicer than (acid) dipped 'pink' copper!
