Hi Everyone, I hope you’re all doing well! Im all moved into my new apartment and I really like it. I’m especially looking forward to my first non boring package here which will come from Severus Alexander. Winning the coins at AMCC 3 prompted my brother to bring out his treasure box of artifacts that he bought a few years ago and we came across this. It’s just the one spot. But, we were wondering how to go about getting rid of it without affecting the rest of the pin. Any help would be much appreciated! Thanks! Erin PS to keep it coiny, here’s my new Tribute Penny. Lol
I think by the time it gets really bad you will be in the nursing home. Maybe do nothing. Just my thought. I have some copper or bronze horse reins rings and they have been like that for 45 years. Perhaps baking soda and water?
...toothbrush and distilled water...gotta cut the air off so it'll quit the reaction...do you have any of BadThad's(or similar) 'verdi-care'..??.. that's what i use and it works well...neat coin Erin and good luck!...keep us informed
the standard method is to mechanically excavate the area of BD, submerge in distilled for lengthy periods of time, literally rinse and repeat until all visible traces are gone.
Hello @Johndakerftw. I'll just copy and paste, the following information, from one of my previous posts. By the way, I have read, in other posts, that quite often, green patina starts as a flaky light green. Then, over the centuries, the flaky light green turns into a hard dark green. Either that, or it destroys the coin. Perhaps it's a race. If the flaky light green, becomes coated with hard dark green, soon enough, so that no more oxygen (or something) can reach the underlying copper, then maybe the coin is saved, and the flaky light green becomes hard dark green. But if the flaky light green doesn't get coated with hard dark green soon enough, then perhaps the flaky light green allows oxygen (or something) to the underlying copper, through the holes in the flaky light green, causing the destruction of the coin. Or maybe, sometimes, a coin starts with a flaky light green patina. Then, somehow, the coin becomes deposited in an oxygen-free (or something-free) environment, which causes the flaky light green to become coated with hard dark green. Somehow, coins with beautiful, hard, dark green patinas are created. I just don't know how, at the moment. Maybe I'll Google it, sometime. I don't know, if any of the above, is true, or not. Maybe someone, with more knowledge about this subject, will comment. Anyway, here is my copied information, from one of my other posts : I'm no expert in this type of thing, so take what I say, with a huge grain of salt. I've had some success, removing stubborn stuff, by putting a coin under a low powered microscope, and using a sharpened wooden toothpick (try this first), or using a very pointy, very sharp scalpel, to push or scrape the stuff away. However, it is very easy, to accidentally scratch the underlying green patina, exposing bare metal (I have had this happen). So you have to be careful. And you have to be lucky.
I agree. Use mechanical methods to remove as much of the bronze disease as you can and then soak in distilled water. Then repeat the operation until all traces of the BD are gone. I've used a dental pick and toothpicks. Good luck Erin.
Thanks everyone! We’ll try the toothpick/toothbrush and distilled water method. You have to bake the pin in the oven for a while afterwards, right? Thanks @sand. I’m actually referring to the pin in the first picture. mom going to leave the Tribute Penny alone because I would do more harm then good. @ominus, I don’t have any verdicare. Erin
I do not think that the tooth pick is going to be good enough for you. you need to get a dental pick made of metal (usually stainless) or some other type of a metal pick and dig out all of the green powdery stuff all the way to the items shiny metal. Then you need to soak it in distilled water changing out the water every couple of days. The distilled water leaches out the sulfates that are causing the bronze disease. You need to soak it probably at minimum of a month or more. Yuo can also check it every once in a while when you change out the distilled water and see if you need to dig out anymore of the area. After you manage to get rid of all of the green powdery stuff for sure then you can dry it out by baking it at a super low temp for about 30 minutes so not to change the color of it. Then you need to find a way to keep air from getting to the area by applying some verdicare to it or possible something else.
