Question for Goes4Ever

Hi Terry,

I have been using your coin cleaning tips - thanks.

Was wondering if you have had any wheaties that look like this - brignt green spots that seem to become more apparent after cleaning. I have scrubbed this with soap&water using a toothbrush, also soaked it in heated H202 for 1 minute, 2 minutes, and 5 minutes, but the spots won't go away. I was hoping that it would turn to the nice brown color that your coppers seem to always be! I have some IH that look like this too - am hoping to perfect a cleaning method before messing with those (I like them a lot more than wheaties).

Any guidance on how I might get rid of the spots?



Thanks!

Try a soak for 1 or 2 days in WD-40. Works good on the coins I tried it on. Just scrub with a bit of soap and water on a toothbrush.

to me those green spots look like verdigris that has pitted the coin, is it pits? If so, you might noe be able to remove them.

I don't know enough about verdigris to know if that is what it is, but it feels rough to the touch, so maybe pitting. Some of the pennies that are caked with dirt and blue/green when the come out of the ground tend to look like this after cleaning. Was hoping there was a cure!

Thanks for the quick response too.

do a google search on "verdigris on coins", there is a ton of info and different methods for cleaning
