Whizzing vs Cleaning vs Dipping vs Acetone

As long as this is only a test piece, go ahead and soak it in a lid of WD-40. Man this stuff will take anything off, such as gum tape etc. It's made up of petroleum distillates, so don't think it will harm the coin if properly cleaned after soaking in the solution. A good rince under running water should do that.
If you try it, let me know how you came out.

I got that stuff here right now--I'll soaking it asap, it would be nice to know what will remove tape no?? thanks oldDan--Thats what this coin is for--test, experiment whiz, whatever, at this point its only value to me is its melted silver value---I'll always have that.. So to me if we can learn in here anything it is well worth the abuse, at least maybe we can learn cleaning effects on silver-- O did forget to mention on the picture answer above, I also tried olive oil--

 

Ok OldDan, looks like (I'm not 100% sure) but the wd40 (soaked for 48 hours) removed whatever was left but it was to late--(obviously)--I really can't tell if the damage was already done originally or not but when you look at that area now under "heavy" magnification (x16 or more) it looks like the silver itself has inherited the pattern (very spotty, has "melted" look and off colored). To me, with the naked eye, still looks like my picture above--

So, if anything learned from this is--DO NOT SHIP RAW COINS SECURED WITH SCOTCH TAPE!!!!--

Next, before I do anything else since it looks like all chemical remedies have been tried (including brasso). It's time to whiz this sucker --(I don't think even NCS can save this puppy now). Since I have never done this (whizzing) before, I do have several types of "wire brushes" some stiff, 1 is very soft if you will. Question is should I hammer it with the hard wire brush and my big drill, or use my dremel and use the soft wire and "gently" wipe it once???? (logic dictates the soft wire)--What you'll think??

 

I got some MS70 to dip some silver quarters with cloudiness. I have read about other people dipping coins in MS70 with good results. The MS70 container states "MS70 is NOT a dip and will not work by dipping the coin. Apply MS70 directly to coin or soak a q-tip in MS70 and gently apply to coin".

So, to dip or not to dip in MS70?

 

Howdy CoinSwede
Can you post a picture of the quarters? AND of this MS70 stuff? I would not use anything on them unless you are gonna turn them into "test peices" if you will and sacrifice them and never try to resell them to an unsuspecting buyer--
I only started to try and "repair" these silver coins AFTER I received them damaged and AFTER I was burnt buying CLEANED $20 Saints, other wise I would not being doing this--Since there are undesirables out there selling illegitimate coins, I had no choice but educate myself--So if you wanna contribute to this education process have at it amigo>>>

 

Here's a picture of the coin and the MS70. The coin picture is a little out of focus, but you can see the milky covering on the coin (proof silver).

 

Wow, I get the picture--Since it is a proof coin, I really don't think anything you use on it will eliminate the "cloudiness". I do beleive however that if you try to use ms70, or like the stuff I used above "might" remove the cloud but I am afraid it will probably remove more than we or you really want to removed--ESPECIALLY since it is a PROOF coin, I'm afraid it might remove the "mirror" if you will or worse -- My advice, move on, the coin looks nice, the cloudiness looks like it was not properly cleaned when it was produced, altho I could be wrong about that--

 

The 1923 looks like some coins that I have seen where Dip-it has been used, and all the brown coloring has not been washed off.

The 1922 looks like someone has used a pencil eraser on parts of the coin.

I have been dipping some euro coins over here in Germany prior to counterstamping them with fun messages. I have noticed that in the “Nordic Gold” coins (very similar to the alloy used in Sacky dollars, but not quite as quick to stain or tarnish) I get wildly different results from dipping. Some of the coins turned a deep golden color (quite nice) in the days after dipping. The post-dip bath in tap water (sometimes warm) might have an affect as well.

Some were in the dip for minutes, others for seconds. I have not noticed too much difference based just on that (but only naked eye inspection).

 

Hi Jim, well on the 1923 nothing was done that I can detect, I have not tampered with it in any way looks like it is developing a pleasant goldish type toning. I guess I could submit it to NGC to confirm that it was never cleaned and if it would contribute to the thread I will, but then my question would be, if it does get slabbed and not come back in a body bag, what do you think its grade would be?

As for the 1922, well an eraser I did not use, and to me was never used, what makes you think that? What has been used so far is Koinsolve, coin cleaner (see thread & picture above), olive oil, WD40, hot water and I'm getting ready to whizz it, I can tell you right now an eraser will not help, even if I try to use it now. I looked at the whole coin using 16x mag and the spots in the area of our interest here, the silver has inherited the pattern, this flaw is imbedded into the silver itself if you will--The only thing that will remove these marks now is grinding, wiring, metal on metal---a gentle whiz might fix it.... What you think?
