I sure would like to see on YouTube...

zap1111

someone demonstrating a successful, safe coin dipping process. I've read the descriptions on other posts. Anyone brave enough to video the process and upload it to YouTube and announce its presence on the forum? Personally I'm interested in dipping as it might apply to CBHs. Thanks.

don't do it

admitting to a crime before you commit it?

zap1111

And yet I read all the time about how a little acetone quick dip will clear out the organic grime yet not hurt the toning?

I'm uploading the video right now...

<< <i>admitting to a crime before you commit it? >>



It's illegal to buy/use eZest?

When did this happen?

doh

WTF? DON'T DO IT!!!

lcoopie

when using the term dip
most imply a dip in an acidic solution, not acetone

Robb

You guys are an odd bunch.

There's absolutely nothing wrong with an acetone bath.

eZest/MS70 is acceptable by the vast majority of collectors and the TPGs.

Justacommeman

an acetone bath is not for me but it's a perfectly condoned practice by TPG's/CAC and a lot of mainstream collectors. I'm curious to see how it's done myself.........MJ

zap1111

Perhaps I'm mixing up terminology (dipping/bathing?). Nothing more than acetone (EZ Est?) in my line of inquiry.

don't dip,,,,,,,,,,

better to let the PVC EAT your coins.

Its called conservation

Great video, thanks, Will!

there is a special place in hell for you.................but thank you

Why do you have a back scrubber by your utility sink?

You can also lay a multiple layer of paper towels down on the counter and press your coin
in between. The multiple layers will absorb the water....

Or you can go from eZest to water then to an Acetone dip...

I would add that it's a bad idea to dip then rinse, then consider the job done. There is still dip on the coin, and since it's a corrosive acid, it will eventually eat at the coin and that will ruin the coin.

After the dip, the instructor in the video should have washed the coin with a mild detergent soap (a base) to neutralize the dip (the acid)...then clean rinse the soap off the coin, and pat dry.

i know nearly everyone gets their fingers wet with that stuff but, it is pretty bad to handle
or be exposed to if frequently. and,you could have mentioned the smell of rotten eggs
if you happen to get a whiff of the coin with dipping solution on it. pew

you might have added an acetone rinse then, a distilled water rinse too i guess
but, tap water will work ok for a general demonstration

Dipping CBH's is a no-no especially from someone asking "how to do it".

ANY COIN that is NOT BU, should never even come close to a coin dip!

End of story.

Great video, but for giggles and grins make another video about over dipping a coin and making it undesireable and ungradable by pcgs standards.

My thought is to use nothing but acetone. It would really be cool if you could post images of the coins before doing anything.
Don't use any type of acid cleaner on these. Acetone should be safe but there is no way to know what the surface of the coin will look like under the junk it may remove. Marks on the coin will show more as well. The junk hides some of this.

I agree. You have to neutralize the acid. There are several things in this video that are just wrong.

Sunnywood

Acetone only removes adherent gunk, not oxides or sulfides. Acetone does not harm coins, nor remove any natural patination.

Goldeneye, after a water rinse, it's a good idea to dip the coin in isopropanol (rubbing alcohol). Any remaining water on the coin will rapidly mix with the alcohol, and then the predominantly alcohol-based fluid on the coin's surface will evaporate quickly. This eliminates hair dryers, paper towels, and those dangerous up and down jerking motions

An even better method after the dip and rinse is to immerse in a warm-water and liquid detergent mixture, then back to a water rinse, and then into the alcohol.

This information is provided in the interest of chemistry and science. I do not dip coins, but have extensive experience with metallurgy.

Goldeneye is extremely proficient at taking a dip, as I recall ... he is a talented swimmer.

I wouldn't say it's wrong, it's just a different (and probably safer) way to do it. I've dipped countless coins and never have had an issue with spotting, haze or subsequent toning.

Greeniejr

You can also use baking soda to neutralize the acid though if you are not careful, that can hairline a coin too.

What worries me is how safe this method is long term.

DIPPING IS DOCTORING!!!

You can only know the effects the acid might eventually have on the coin if you lived another 75 years or so to find out. Taking the acid completely off the coin by chemically neutralizing it guarantees the acid will not remain on the surface. It's actually a part of proper dipping 101...NEVER leave the acid on the coin.

Thanks, GoldenEye for the video - it was great just to be able to see the process being done. I figured this thread would stir up the usual brew of mixed opinions (one of the things for which this forum is well known). I appreciate 19Lyds advice about CBHs - when I saw GoldenEye's coin after the quick dip, that's exactly what I don't want to have happen to my coins. I'm more interested in removing debris. The notion that the debris at times hides even more troubling impairments is duly noted. Thanks, everybody!

Use just a little dip and place snuggly between the lower lip and the Jaw.

Most important always spit NEVER swallow.

Rinse with beer after the dip.

if you drip then you can pat with a paper towel

tjc2120

Wow, always wanted to see that.

Goldeneye, can you demonstrate with some old copper and gold and post before and after pics or shots of the coins?

Just trying to learn the dipped look a little better.

Thanks for posting the video.
