Yes, I would care. If I were presented with the two coins in your OP, one being original and toned, and one being blast white and clearly dipped... I'd pick the original one every single time. Yeah, that's exactly it. Also.... I don't really care where you went to school. I do care that you use proper grammar and punctuation. It is considered good manners on a forum such as this.
Before the cleaning... maybe 65 After the cleaning... 64 And it is obvious you (or someone else) cleaned it. Don't try to play coy with us. The before and after obverse are clearly the same coin.
I'm not sure if this is a good coin to prove this point but It's what I'm willing to sacrifice. I understand. Does electrolosys change the surface material or just remove contaminants. I've heard that is how PCGS does restoration.
I'm currently at 4 glasses of bourbon. I'll bet @green18 probably has me beat. But I use a spell checker. What's your excuse?
Cleaning and conservation are two very, very different things. The difference between them has been discussed at length many times before. They should not be confused! The coin in the OP was cleaned - it was not conserved.
The difference has been determined by a hundred years of numismatic practice. There are commonly accepted definitions of each term. I'm not going to get into it now, both because this thread isn't worth it and because it is easily searchable if you cared.
