Second attempt at retoning listed Well, I recently recieved a few coins that were clearly dipped, so I decided to make a compound in lab to retone coins. I started practicing on some old wheat pennies, and they have turned out okay. What do you guys think of this artificial toning? Please note, I would never sell a coin that has been artificially toned, I am simply doing this so my pennies do not have that fake ugly orange color. Update* see post 10
Zaneman...what ya doing in the Lab? School? Job? Mad bomber? hhahah LOL just kidding on that one... I work in Lab's as well cell culture work... What ya using? RickieB
It sure does make the wear points stand out doesn't it ! All in all I'd say ya did pretty good. You'll have to work on the dark areas though
Is that what's in the "antiqueing" compound that's sold for giving an artificial patina to brass hardware?
I'm not sure, I can think of about 20 different compounds that could tone copper. I would imagine that it does have sulfur though.
Although I would not recommend this but copper coins placed in between the folds of a piece of aluminum foil and placed in a oven pre-heated to 200 degrees for 30 minutes to 1 hour, does a pretty good job of toning. However, coins that have a higher or lower than normal amount of tin and zinc mixed in the composition, may take less or more time to tone and may even come out a bright orange/red color. Frank
I've heard that this stuff works pretty good but I personally would (almost) never try it.hehe http://www.collectors-outpost.com/product/R1005
Looks good zane, I'm wondering how thay will stand up the test of "time". Guess we can wait and see what they look like in 20 years. Right?
I haven't worked on those yet, as I don't own many. However, I will start that soon I'm interested in chemistry (35 credits at college level), and I love coins, so it seems like a good interest to me : )
I have also messed with re-toneing silver coins in the past that have been bought cheap due to cleaning. I have been fairly good at it from time to time, each coin is differant and will react differant. I have used a bottle of "Gun Blue", reduce it with acitone to the right trile & error mixture, then clean the coin with acitone first, then heat it up warm, not to hot, then drop it into the salution in a bowl, quickly pick it up and rinse under cold water, pat dry with cloth (dont rub), then apply a little oil to surface to stop any further chemical action, some have turned out wounderfull! rainbow colors and some not so great, trial & error.I showed the coin to a dealer I got it from 3 months later and he offered me a fair price and didnt know the differance!!!!!!!then I broke the news to him and still bought the coin back.......As said, you need to mention a re-toned coin for sale to anyone.
