Diping coins?

sborder285

Can someone clearly explain or post a link on how to correctly dip a coin? What chemical would i use along with the equipment?..is the process diffrent for proof coins?...Thanx

First decide if dipping the coin will ruin it.

If not you can use acetone or sulfuric acid. If those don't sound like friendly chemicals it's because they are not. Use rubber gloves.

You can buy acetone at Home Depot. Sulfuric acid is sold diluted for coin dipping as Jewel Luster / e-z-est like this



Using dip, put the coin in for about 5 seconds lightly swishing it around. Rinse off the dip immeadiately and completly. PAT the coin dry with a paper towel (never rub it or you could scratch it). If you can get all the dip off and the water rinse off, it won't form any spots later.

Thanx for the advice. I just brought my 1971 Bahama Proof Set back to life. Got a 1884-0 Morgan in Pl 62 ANACS holder i'm thinkin of dipin and sending back in. Would ANACS slabb it cleaned because of the dip? Yeah, it's not worth money to have it regraded, but i feel safer handling proof coins in slabs, don't damage as much when i drop them

Dipping is an immoral practice that destroys coins for future generations of collectors. All coins, no matter how ugly, should be left "original".

I disagree. I agree. Ahhh I really don't care.

russ, There's absolutely no circumstance in which u'd dip a coin?

Boom

This is ONE time I actually agree with a certain Board Member, however if you are of the mind that you absolutely MUST dip your coins, a very close friend conveyed the following to me and it seems to work
It's a 4 part process. Leave any one of the 4 parts out and in about 70 days you will see the adverse chemical reactions take place on your coins. I don't advocate dipping!
1. Dip the coin for 5-10 seconds lightly rubbing the coin
between your Index Finger and Thumb.

2. Rinse the coin in clean DISH of SOAPY water for 15 to 30 seconds.
**DO NOT leave this step out!

3. Rinse the coin Clean Fresh Water for at least 1
Minute.

4. Throughly dry the coin with a clean bath towel. DO NOT RUB or you can get hairlines!

The tough part is knowing which coins can be helped with a dip.

There is always a risk. Too many are made worse than they started out.

!?I think it's on1?..or maybe i'm just being retarted

Can diping remove PL or DMPL appearence from a Morgan and would ANACS label it cleaned if there weren't any canges to the coin besides the color change. As opposed to the hairlines which are abundant on the coins labeled "cleaned" from abrasive methods.

If it was on there would be a padlock visible in the upper right of the message area. Go to the top of the page and click on profile and where it says display profile visibilty put a check there. Thats all there is to it. When you want to send a PM simply click on the padlock when they are online.

Just fixed the PM thing, sorry about that...

The pic attached is the coin i wanna dip, i posted it here a while ago for another reason. I truly believe that there's a beautiful DMPL under the "Toning".. It also has some "Crud" on it in various places; dircetly in front of liberty's eye and right in front of the date. THe reverse also has plenty of hazy toning and a few areas with crud on them. I just don't wanna dip it and completeley ruin the coin, i've tried this on many other MS and proof coins and for the most part they all returned looking a lot better than they were.

DMPL Morgans do not often dip well. I had one with tan hazy toning I sent off to NCS. Some of it was removed, but not all. That hazy toning seems to etch into the mirror surface. The dip removes the toning but the haze is still there.

the only reason diping this coin even crossed my mind was because, as mentioned earlier, i dipped a my 1971 Bahama Proof set. All of the coins were left out in the open display case near a window and they were covered in dust and grime and barley recognizable to be proof, meanwhile, the reverse which was not exposed, still retained it's flawless Dcam apperaence. I went ahead and dipped them and the coins came out brilliant, all with nice cam obverses. It just seems that if a coin with even more build up than the morgan came out brilliant, the morgan should also.

I had a Morgan come back in a body bag last year, "cleaned". It was probably one of a few that I had dipped some 10 years ago. However, the Morgan had a beautiful, cartwheel luster when I sent it to PCGS. I thought dipping would cause a dullish, grayish appearance on silver coins? Or, at least remove the cartwheel luster?

Over-dipping will. Properly done dipping won't. This coin was in an NGC MS66 holder and covered in ugly mottled brown toning. Cracked out and dipped:



It's now in a PCGS MS66 holder.

And tomorrow it could look like this. (sort of)



One of the things that really burns me about dipped coins in holders is that if the stuff is not rinsed properly, the coins turn color. This can be REALLY bad on delicate items like Proof copper. The results can be a disaster. Sometimes you can pick these things up, but not always. It's the ONE way that experienced people can get burned rather easily.

Russ

<< <i>And tomorrow it could look like this. (sort of) >>



Not hardly. I have coins I dipped nearly two years ago that haven't changed even a micron in appearance.

Russ, NCNE

BillJones

Yes, I know Russ, and it's probably because you did the dipping. The point is that a lot of these guys just dip, submit and turnover quickly, and the coins tone.



When I bought this 1861 silver three cent piece in March 2003 it was bright white. By summer it looked like this. I'm still happy with it, but not all coins end up like this. At times its a lot worse.

Russ

Bill,

I agree. There are plenty of coins out there with the telltale golden toning that develops around the periphery and then works it's way in to the centers. It comes from not neutralizing the dipping solution. If a coin is properly neutralized, it doesn't happen - at least not with silver. I don't know about copper or clad because those I don't dip.

Actually it contains diluted sulpheric acid and thiourea (thiocarbamide) here's some info from a website on Thiourea:



<< <i>Character:A White,glazed crystal,bitter,soluble in water,decompositing when heated,being complex with a lot of metals and inorganic salts.

Use:Used as thiazole medecine such as sulphathiazole,tetramizole,thiourea dioxide and a medium of medicine curing thyroid gland.Intextile industry,it's used as a bleaching agent,dyeing agent and antioxidant.In the proeess of making a blueprint paper,it is characterized by distinctness and fadelessness.In photo industry,it'used as a stabilizer of developing emulsion and fixing bath.In the process of extracting gold, it can replace the intense poison cyanide. Incopperplating and galanizing barium,it can devide equally the deposition of matals,improve the stability of electroplating solutiom and gain the lustre surface on the plating material. It's also used to clean accumulated filty in the high-pressure boiler and as a synergist for nitrogenous fertilizer.It can cure the mildew of oranges >>



I think if you just use sulphuric acid you're results won't be particulary good - but then again, dipping any coin often has bad results!
