So I was doing some coin doctoring today....

Used some MS70 on a gold coin that had some haze on it. the lighting techniques are different but you can see the difference.

I hope I didn't offend anyone by doctoring some bullion. I like it better.

Removing haze on a proof coin is a good thing. I use Coinsolv for this, and it works great.

Beautiful coin!

I don't know how many would confess removing haze from a proof coin is considered Coin Doctoring. I suppose a few- but I'd think mostly not.

I think it looks much better. Anyone who considers what you did coin doctoring needs to have their head examined.

I had a feeling about you, Doctor!!

More like nursing it, I suppose.

nice work

It looks nice!

Growing up through the years in the hobby have usually heard this referred to more often than not as conservation.
And normally actable on proof coins.

Curses to all of you for not putting the phd at the end of my name! lol

That's not a doctor. That's an "In Turn"

I'm a strong supporter of mindful conservation. In this instance, not being clear about the purity or possible alloy, all I can say is it worked, and it looks fine for what it is

I think Coinsolv would be a better first step as it is essentially inert. And more effective than acetone in many instances.

Not only do they all have their uses, there's a hierarchy of non-invasiveness of solvents relating to deposits and the way they cling to surfaces. I've got to get me some Xylene and play, and I'll miss tri-chloro-tri-fluoro-ethane (Dissolve) to the end of my days.

I only work on pre-1933 gold, and have conserved millions of bucks of it over the years. Use of MS70 on proof coins of that era usually ruins them as far as many traditionalists would be concerned. Ask RYK for a definition of "crusty". True for any US Gold 1933-earlier.

Pruebas et al. "Removing haze on a gold coin is a good thing" ?????

Try "Some gold coins with haze look better when it's removed, and this sure was one of them !"

Different conservation "rules" for different years and dates and types and metals. Solvents, emulsifiers, acids, bases, dilution, duration, vibration.... Damn!

edited to add: But for a lot of coins they're fairly simple, and the techniques/processes/chemicals are transferable from one sort of coin to another, even across metals.

Alright !

Now just get some accounts. Hang out a shingle.

Next week start looking at BMW's.

I've never used Koinsolv before, can anyone give some information on how it works? I would prefer not to use acetone due to the fumes. How is this on fumes?

Well done doctor!
