Clouding on Proof Silver Coins

I always found MS70 really effective for this, though if the formula has changed I don’t know which version I was using.

More recently I’ve been using a sodium hydroxide solution, of about the strength people use for making pretzels. The thought was that NaOH isn’t that different from KOH (one of the ingredients in MS70) and that I’d rather expose a coin to one agent than several if the result is the same. I’m certainly not urging this treatment on the OP, but if there are any other mad experimenters about with hazy 1970s proofs - well, it’s working as well as MS70 did for me.

 

I'm pretty sure they claim it hasn't, but I swear it seemed a little stronger a couple years ago.

 

... or were coins just more, ohhhh, co-operative back then?

 

Forget dipping or cleaning. Just buy a better coin, one that doesn't show what you're describing.

 

WELL SAID, but as I casually peruse "brown Ikes", I'm finding "clean" ones harder and harder to find. I don't know what this means exactly, but it seems that the 1974's are the toughest to find without haze. I might have suspected the opposite. Whatever is its proximate cause, they seem to have beaten it for the bi-centennial 3-coin set.

 

Usually I agree with this sort of advice, but this seems to me a special case where the cure is particularly easy and reliable, so I don’t see a downside. (If I could get the same consistency of results with Ezest on ordinary tarnish, I’d be a genius.) YMMV of course.

 

I thought it was "Verdi-Care" that had been noteworthy for fundamentally changing its formula, or am I mis-remembering?

 

I’ve heard it said about MS70 before now, but not about Verdi-Care. But this is more a gauge of which random rumors have made it down here to south Texas, than anything else...

 

In my area non blue haze are not available. I have looked through tons. I have 2 73's that have a groovy blue tone to them though.

 

Entirely possible that’s part of it.

Did they? I’ve never really paid attention to that one. I don’t like having to do anything to copper

 

It's a Pennsylvania thing. Copper has ALWAYS done well here, unlike western states. The soil here is "rotten with" copper coins, both pre-federal and since. Just about EVERY serious metal detector I know has found a three-digit number of early coppers. Most need some tending to.

 

Jus' sayin'. So far, New England WHO????

 

Han Solo Trailer!

 

If I lived around there I’d probably spend a little time metal detecting too

 

I haven't pulled that particular trigger yet. I may when I retire.

 

Boy is Amendola a punk jerk, or what? I ordered my Nick Foles #9 Super Bowl LII jersey just as the game began, and I'm loving that the urge hit me.

 

Did you try Scotch? If you haven't any, you can make it. When you're all done, you can drink what's left. Here's how...

 

Okay. but what IS Coin Care used for? BTW, we, especially on THIS site, and almost nowhere else I ever get to, are in SERIOUS danger of overusing the word "dip", and ruining its informative usefulness for that reason. In the general parlance of this field, NONE of the following are "dip""

Verdi-anything
MS70
and ESPECIALLY not acetone



What IS dip?

Thiourea plus an acid, a solution intended to remove sulfides from the surface of silver, PERIOD.

And somebody please pass me a facial tissue, not a Kleenex.
