For the price of a pizza, I think it's worth it to at least try. I bought a bottle a few months back, haven't tried it yet as I lost the directions but from the results I've seen it does the job.

Its just got me thinking, that if ever a chemical that can clean a coin to MS-70 fast and cheap, I'll hate my life cause then coins wont be rare anymore in higher grades. A G-4 is worth a MS-70 cause you can make s MS-70 easily.
You cannot reverse die wear, circulation damage, nicks, and scratches in your coin. I can't think of such a product that could restore the patina of a well-circulated coin to mint-state. So I don't think you have anything to worry about.
I probably did it wrong, and I used about 1/5 of the bottle (12ml) in the process, but here's my first test with VC. It seems to work as advertised, and I think it did a terrific job of conserving what I now believe to be a fake coin.
That's yet another advantage of it. You get to call the finished product "conserved" rather than "cleaned." On that coin sniffer, I'm just curious. Is anybody taking that thing seriously? What I mean is, has anybody here submitted at that level or paid a premium for a coin submitted at that level? The last I heard about SecurePlus(TM), and that was quite a while ago, it was basically just after it came out, everybody seemed very excited about it. Well, except me, I kind of have a slightly different opinion. PS: Put me down among those who endorse Thad's product, too.
I submitted coins last week under SP. I think that means 10 more (business) days before they do the 15-second review at the last minute to make the 15 day deadline. After looking at the Sniffer video, I figured out "how" it would detect VG, even though it shouldn't be able to. They're testing the coin RIGHT AFTER it's been applied, so VG wouldn't have evaporated just yet. So, if you want to submit your coin at a show right after using it, go right ahead... the Sniffer will catch you.
Its actually algae cleaner for your fish tank. I Wouldn't Recommend any type of protective layer. What you keep out is also what you seal in.
It is a good product for what it does. If you have coins dying from verdigris, it can remove a lot of it and slow it down from reforming. Forgive me but I have cleaned (yes, Doug, harshly cleaned) coins and now regret it. The worst was a nice FE cent I cleaned which subsequently turned pink and then a really nasty brown. I re-cleaned it and treated it with Verdi-Care, and it has re-toned nicely. Please don't judge me too harshly.
Where did this info come from? Do you have anything to back up this claim? The developer of this product is a member here an I'm sure he would like to know how you came to this conclusion.
Evidently, you didn't take organic or metallo-organic chemistry, or you might have a different opinion.
Don't mean to disparage the product , but came across the info several years ago from several professional antiquity restorer's who have been using algae cleaner for years. Its been a bit popular lately for bronze disease in the ancient coin community. Buy it and try it. Use a weak dilution until you figure what's best for you.
Information can be shared without backing it up, but it usually will be ill received. You may be talking about the use of copper sulfate solutions, but Verdi-care and previous Verdigone are not in the same chemical basis. I had doubts years ago also when Thad was working on his first product and tested it many times, you can find the threads on the site, and found it worked, and the coins would be graded by TPG with no indication of use. He is an industry chemist and has the background. You may "poush" it , but for non-ancient coins , the product can work miracles and I have never seen a real case of any damage from it's use. If the info is valid, you are welcome to post it, but there may be discussions on its value. Jim
These professional restorers may have used Algae cleaner but this product is not what they were using.
