Latest NCS "Conservation Coin of the Month"... not sure if it's better.

The before pictures definitely show a "dirty" coin, but there is some underlying color that is utterly destroyed by the NCS process. Yes the after pictures show a cleaner coin, but you can still tell that it has issues.
I would have left the coin as is... to me the "before" coin has more character to it. The "after" looks lifeless to me... *shrug*
NCS commentary:
Residues can be more than just ugly obscuration of a coin's surface beauty. Residues can also eventually lead to staining and worse, environmental damage. Over time, offending residues can eat into the surface of a coin, permanently altering it chemically. What numismatists refer to as staining appears as large areas of dull white or grey-black on the surface of a silver coin and may result from active residues. Further damage by offending residues will cause a coin to be called “environmentally damaged.â€
This particular proof Walking Liberty Half Dollar was saved by the professional conservation techniques employed by NCS conservators. Removal of the thick residues left the coin free and safe from the potential staining that plagues similar coins. This coin graded PF 66 with NGC following the conservation.

But yes, the first one is much more ugly.
nice coin, but it looks cloudy. And the stain lines are still on the coin, almost like a fingerprint. especially on the left sde of the coin in front of Ms. Liberty. They can't remove them?
Too many positive BST transactions with too many members to list.

"Keep in mind that most of what passes as numismatic information is no more than tested opinion at best, and marketing blather at worst. However, I try to choose my words carefully, since I know that you guys are always watching." - Joe O'Connor
I think that I actually like the before pic just a little better. But, not by much.

No one wants to add a $500 coin (or whatever that is worth) to their collection that looks like that. Maybe in "theory", but not in reality.
We specialize in original, untampered with coins, but what that really means is "original coins that look attractive to collectors". We have had completely original, untampered with coins in our inventory, but unless they are attractive to the eye, it doesn't matter. We'll end up putting them in an auction unreserved after a period of time with no collector interest.
Edited for clarity.

The after picture is plain horrible.
