Can this be cleaned?
« on: October 16, 2012, 11:58:07 AM »
Hello,

I came across this coin recently. I want to know if there is anyway it can be cleaned.

I would like to buy the Bull Anna series.

I will also buy single coins of this series.

Please message me with your price and an image of the coin/coins.

This coin is for sale and you are asking a commercial question on a non commercial site.

Questions on cleaning make sense only when you know the metal and have an idea about what the sediment is. When all the info you have is a picture, you can only take a bet. Take into account that the seller may have tried to clean it already.

The seller says the marks are caused by oxidation and he has never tried to clean it or has even touched it.

The metal is cu-ni.

I have seen the same marks on some of my friends proof coins too.

It will be very hard to clean without wiping off the patina and even so, the affected places will probably remain dull, so if the rest of the field is shiny, you will continue to see where the spots were. With time and pollution, patina should return.

Copper-nickel does not "oxidize" easily. this looks as if it has been exposed to something stronger than water. If you really want to try and clean it, use baking soda mixed int a paste with liquid soap. apply to the coin and rub with a soft cotton cloth. It will take some work, but the corrosion should polish out.
