Dipping a DMPL

robertpr

I've got a few nice DMPL Morgans with a touch of haze in the fields I want to get rid of. Will a dip kill or lessen the mirrors at all?

I've got that problem too and am even afraid of minor PVC. Hope somebody knows!!!!

The good news is that if you screw them up, you'll lower the populations, making your remaining dmpls more scarce and more valuable.

I actually asked a local dealer that once, he said that it's too risky to even try. I don't know how that exactally can help you though.

Dip usually hurts mirrors. If you want at least some value protection, I'd recommend sending them to NCS.

The chances are you will bring out things in the coin you don't want to see.
I feel the same with early proofs. I learned to enjoy them the way they are.

You can dip them - BUT - you must rinse them immediately in distilled water for a while. DO NOT do it if you just have tap water. Leave them in the dip for only a couple of seconds and then rinse, rinse rinse.

Another method is to use acetone - dries out quickly and will quick clean the surface. Again - rinse, rinse rinse, with distilled water.

Either method - damp dry with clean, soft cloth.

Good luck

I've never damaged a DMPL dipping it. As with any coin you dip, only dip it for a few seconds and immediately rinse it off with water. I've never used distilled water, only tap water. Coat the coin with straight Palomolive, rinse with warm water, pat it dry and use acetone or lacquer thinner to ensure any residue is totally gone. Apply the acetone or lacquer thinner in a circular motion with a Q-tip.

Acetone doesn't need to be rinsed or patted afterwards. It dries in seconds. But if it is true haze (as in toning) then acetone will have no effect. If it is surface contaminants causing toning then acetone will help. 100% pure acetone, only.

What can be hiding behind the haze is what scares me to death.

It won't hurt them but it usually doesn't help the haze either.

If acetone does not work, what should you use? Jeweluster or MS-70?

OK, I just tried 2 DMPL Morgans. I left them in laquer thinner (automotive) for 15 minutes and then patted dry and rinced with acetone. One completely cleared up and looks like new the small oval hazy areas in the fields COMPLETELY gone. The other Morgan didn't change a bit. I might try some jeweluster on a common DMPL tomorrow but need to find some distilled water or more acetone.

What about baking soda and distilled water?

Or a shotgun, or maybe a file...

if anything, the mirrors on a dmpl (or proof) coin will be LESS damaged then the cartwheels on a business-strike.
