The colors look a bit more vibrant, less muted, in the after picture

That's a great looking coin. It's a definite improvement.

Thanks guys!
Sometimes, when I dip a toned coin into acetone, some of the colors would disappear? This time, the colors pop even more!
The acetone made the area near the date, more clearer.

Once that layer is gone things can pop
Chemically, acetone won't touch the toning that occurs when the surface metal reacts with the environment. Any changes you see after an acetone soak are due to removal of organic adherents, not the toning.
If there is some oil on a coin it can sometimes give off colors that can disappear if you remove the oil with acetone.

Yeah, like you guys mentioned. It's the organic oils that appears to have colors, being removed after the acetone hit it! In my case. This is when it's a true toned coin.

While the coin is sitting in the acetone, it allows light to reflect off the surface of the coin without refracting as much through the toning. I've found that shining a light on a toned coin while it's submerged in acetone lets me see under the toning, it's a useful method to determine if a coin is a candidate for a dip or not.
Just don’t use the pink kind with perfume in it
So if I submit my blazing gold toned MS 65 Buffalo for conservation for minor pvc is the coin going to look better, worse, or the same? Please advise. Thanks
Your acetone soak has confirmed the fact that you have a tarnished Kennedy half dollar.

If the toning is caused by the metal on the surface reacting to form oxides, sulfides, etc, then acetone won't touch it. If the toning is due to a thin film of organic contamination, then there is a good chance that acetone will affect it. So it depends on what's causing your toning.
However, PVC plasticizer residue, will react with moisture and form hydrochloric acid, which is never good for a coin. The longer it stays there, the higher the probability of permanent damage
Like it a lot.
My first experience with acetone dipping is your above pictures.
Thanks @joeykoins
