    Restoring cleaned coins

    As this is a sore subject to many, im sorry if this bothers any of you. I consider it less of a sore subject cuz I have no interest in value of my cents for selling purposes, i have no valuable ones any how, accept special coins which i use only water.
    So When I began collecting wheats I used different mild acidic substances to remove dirt and such (vinegar or lemon juice. alternatively hydrogen peroxide on a few since i read somewhere it wouldnt harm them) but after sitting for a long time they had developed a horrible oxidized look, They appeared perfect like brand new when i initially cleaned them, the normal crisp copper color, nice in my opinion. So in an attempt to give them back some more original color, is there a substance , maybe like that Verdi-care stuff that would help return the wheats color, Im not saying the patina, cuz that takes time, just get rid of the oxidized orange/pink color. I know the weak acids remove a tiny layer of the coins surface but there must be a way to give it back the look they would have had.

    Now please understand, this is not intended to scam anyone, this is my collection and i know i "ruined" them but id honestly like to know of any way possible to fix the damage iv done.

    Thanks for any constructive opinions

    You can only let them re-tone over time. Hope they go back to something normal, but they rarely do. Leave them on a wood window sill for a few months/years.

      Buy Some Dellers darkner. A few eac guys in my club use it. I know they completely strip the coin. Then a quick soak in xelone. Then apply the Dellers. Some of the late date large cents turn out beautiful. It's about conserving old copper to them, and is a common practice in the side of numastics.

          Jason is right but since they are little to no value to you, you can also try cent toner. I tried it a long time ago but don't care for it, but it will give it a darker tone then having pink color. There's nothing to bring back the true bright color, not unless you eletric plate a thin copper coating which is very hard. To much copper and the coin looks bad. To thin then the letters stick out a different color. It's a hard thing to do but I have seen it done. Best to just let them sit in a window where they get alot of sunlight. Or try the toner, which you can remove right away if you don't like it.

              Most of your b&m shops carry it. I know you can buy it online.

                  Stick them in your pocket and carry them around for awhile.

                    You don't need there brush to use. Use a small paint brush like what you use to paint a model or maybe even a Qtip. There brush is a small brass one and it will scrach your coin.

                      I've had relative luck putting them in a paper bag and sticking them in the corner of my closet over a few months. I'm not sure if you ever completely cover up the old cleaning. Experiment with a few different methods and see what works best.

                        Yes, B&M means "brick & mortar" meaning it has a building not just a mail order seller or whatever.

                          None of the solutions you used are "mild", in fact, they are all extremely harsh on coins. In general, acid (vinegar, lemon juice) + metal = BAD. Peroxide is also very damaging to coins.

                          VERDI-CARE™ will not retone coins. It is simply a corrosion and surface debris remover.

                          Unfortunately, your coins are ruined forever. The natural color will never return, they will always look funky even if they retone. A harsh cleaning cannot be "undone".

                              I have a 1915-D RPM#1 in a original paper flip/coin holder that i've been trying to tone down for better than 6 years - direct sunlight. It has toned back somewhat but not very much. I've met dealers over the years that clean everything in the early stuff - 1915-1933 because it gives the coin a new look for them to sell at a higher price. Most of these coins naturally grade AU+ - That is why you must really check the condition before purchasing, and if the color is a bit off, Let it go. One friend I know had a 27-D RPM#1 in AU++ and he dipped the coin so he could get $65.00 for it. I was sick when I saw the coin, what a waist!!!
