The six coin Verdi-gone trial is

located here.

1.5 hour soak for each coin after a dip in xylene as recommended by verdichemist. You be the judge.

Seems like everything that was done (doesn't look like much?) would have been accomplished by just the xylene dip?

Good observation.

What is apparent to me is that copper just doesn't like to be chemically played with.

19Lyds · May 20, 2009 5:33AM

Copper just plain doesn't like anything except turning brown!

Probably the most unstable metal used in coining!

Thank you for taking the time to take the pictures and post the results.

It would be nice to see coins that had no other problems other than verdigris so that the eye is not distracted as easily. Coin #6 fits that bill and it's results seem to me to be the best of the bunch but eve it's "After" result is ho-hum. After seeing the results on multiple threads and the somewhat hostile responses by the inventor and his sales rep, I'll avoid this product.

On the most mild one it did seem to get rid of much of the verdegris. The other ones look hopeless and have more problems than minor verdegris.

Not to knock the experiment or the stuff. It looks like the coins that would benefit are ones that are otherwise ok but just starting to get verdegris. (caught in the early stage)

It might need a little help, maybe gently nudge the verdegris spots with a soft thorn while it's in the solution so it has more chance to get the verdegris off without a long soak.

I am begging all users to NOT use xylene as it is incredibly toxic, and even once used safely must be disposed of!!!!!!

I just have not seen this product yet to demonstrate its worthiness. Maybe more studies will show, but for goodness sake stay away from xylene.

I think its a big component of charcoal starter and related petroleum distillates.

If one has access to an ultrasonic bath that might help things a bit.

I normally don't keep such items here at home, but verdichemist used the non use of xylene to remove organic material on the first coins I used Verdi-gone on as to the reason for color changes on the copper.

ldhair · May 20, 2009 8:27AM

It looks to me like some of the green came off. Having to scroll up and down makes it a bit tough to really compare the two images.
It would be cool if the images were about 500X and left to right (before and after) so they fit on the same screen.

Some seem to have a small color change and or a bit of a shiny look but I can see a good use for the product on some copper.
There is something that worries me. Many coins that have spots and the skin removed don't look all that nice over time.
I guess time will tell.

Amigo · May 20, 2009 8:42AM

I recv'd my bottle promptly after ordering last week. I have used it on 4 coins in varying stages. My opinion is that it's not a miracle cure, but it greatly helps the less aflicted coins. I'm very happy with the product. It did not change the coin's toning.
I am not a photographer ........ just stating my opinion.
I will continue to use it.

BTW, great job with the photos.

ArizonaJack · May 20, 2009 9:02AM

Pretty decent results for an hour and a half, and thanks Ken for the post. No blue coins I see, lol.

coinman420 · May 20, 2009 9:32AM

i also bought a bottle to try it myself. i posted pics of 2 lincolns in the original thread that i would try to clean up. one had a little verdigris and the other a lot. i soaked for an hour and had other things to do so i rinsed and looked and results were good. the one with a lot of verdigris still had some and the other was verdigris free with almost no color change. certainly no red color. i put them away and have not gotten back to it to photograph and post before and after. i think a big factor is the two i did had no other problems.

kaz · May 20, 2009 9:39AM

thanks for posting the results, it seems to work pretty well on the areas where the corrosion hasn't eaten into the surface too badly, and the overall coin color does not seem to have been affected very much. Good experiment.

Steve27 · May 20, 2009 10:04AM

It appears to do a good job on small amounts of verdigris, but leaves a cleaned reddish looking area where the verdigris is heavy. As for xylene, it does nothing for verdigris. (If you have some and want to get rid of it, the best way is to burn it, but be careful it's very flammable. As for toxicity, it's no worse than a lot of household cleaners.)

Bochiman · May 20, 2009 10:39AM

Ok, I have some lincolns with verdigris but am too cheap to buy the stuff...if anyone doesn't want theirs, send it to me and I will test it as well

Is that you, Cherwood?

RedneckHB · May 20, 2009 10:49AM

Great results. Looks like this stuff does as advertised without turning coins neon as insinuated in the other thread.

You smooth talker you! You just want me to stand on my head with a Happy Happy Joy Joy sign, don't you?

VERDICHEMIST · May 20, 2009 1:16PM

Ken, thank you for the honest evaluation. The pictures this time are absolutely top-notch and are completely representative of how VERDI-GONE™ works.

Jack and I are not out to deceive or make claims that VERDI-GONE™ is magic, it is not. It is simply another tool in the collector's arsenal. All I ask is that people evaluating the product give an honest opinion and post honest photographs. That is exactly what we have here. I've taken the liberty of putting the pictures side-by-side so that others may clearly see your results. The "before" pictures are on the left and "after" on the right.

1Mike1 · May 20, 2009 5:28PM

Looks like this stuff may be good to salvage a coin from being totally destroyed by green. Most coins that are coated in green are not worth playing with unless it is a key coin that still has value even after it has been cleaned. The coins that Ken had photographed turned dark with the exception of number six which suggests maintaining patina may not be so easy after all while trying to strip the green off.

gmherps13 · May 20, 2009 7:12PM

a little difference can go a long way with coins...great job, IMHO

halfhunter · May 20, 2009 10:37PM

Would a second soak help remove any of the remaining verdi.?
Would, as suggested, "working" the area, while soaked in the solution with a toothpick or rose thorn have any effect?

Regards,

John

Absolutely! Ken only ran the test for 90 minutes on each coin. As in the directions, it's recommended to continue the soaking until all the verdigris has been removed. Physical action is recommended to remove stubborn deposits, I've used both a toothpick (with a tapping motion, no rubbing) and, for the first time, I tried a rose thorn. The thorn is quite handy for very small crevices, but you have to very careful not to scratch the surface.

CaptainRon · May 21, 2009 8:27AM

Contrasting results in my opinion from a previous post. However in the previous post, did the coin in question have any remaining luster.

That is what I would be inerested in seeing, what it if anything it does it do to the look of a nice cartwheel luster.

telephoto1 · May 21, 2009 9:30AM

Sorry to be a wet blanket here guys, but frankly, I am totally underwhelmed by this product.

I've been wanting to give this stuff a fair shake and even considered stocking it if I thought it worked well, but based on the results I've seen thus far on all the coins that have been used for testing, both here and on the other thread...though this stuff does indeed remove verdigris to a degree, frankly I see nothing here that could not have been accomplished with distilled water, some coin care and a toothpick. I've even seen better results from the use of olive oil, on pieces far worse than the subject coins.

I know I'm going to get hit with the "no 2 coins are alike" argument and/or get flamed for saying what I'm saying, but can anyone here honestly say that they are WOWED by the results seen here thus far? In the "after" pics almost every coin still has remaining visible verdigris, except for coins that had very little in the first place.

Let me be clear; I'm not saying that the stuff doesn't work at all, and I understand fully the assertion that it's just another tool.... I'm just saying that based on what's been presented here by many people (including the manufacturer I might add)...I'm not impressed. Sorry.
