Cleaning tip needed

Just wondering if anybody has any tips on how I might soften-up this green stuff so I can remove it and see some more of this coin. Thanks.

A bowl of hydrogen peroxide should clean it , I know they use it on dug up pennies .

Be gentle - start off with a soak distilled water.

 

I know distilled water is the gentlest to start with but isn't hyddrogen peroxide just water with a little different chemical bond .:smile:hatch::hammer:

OK, then, it's settled. It goes into distilled H20 for the first couple of days and if that doesn't work I double the O atom and try that. Thanks, guys!

 

Eddie I'd wait a while longer , a lot of peeps go online after work , they might have some good ideas , or PM GD he's pretty good with coin chemistry , just a suggestion .

OK, I guess I'm just a little impatient. :headbang:

 

Peroxide won't get that crude off. Only way to get that off is to buy some arm and hammer washing soda NOT baking soda. Line a 6X9 glass pan with aluminum foil fill two thirds to the top with boiling hot water. Put in 3 big tablespoons of the "washing" soda. Plop in the coin until the fizzing stops. The green blob will be gone whats left of the coin underneath will be shown. Most of the time under the blob of green it is pitted pretty good. Sometimes but not many, you get luck and it comes out ok. Thats the only way I know how to get those blobs that look like that off with the least damage to whats underneath. Jim

 

Jim, thanks. Do you see this green in your detecting finds? I'm curious what it is, as it sits on the surface, and, as you seem to know, isn't corrosion. Also, is there an "economy-size" setup I can use (such as an old glass mug), instead of the foil-lined 6x9 Pyrex pan? Just asking, now, as it's only one little cent...

 

I would like to know this as well...

 

Thanks Jim, I will also try this with my basketcase 1931-S

 

Water cannon?

 

Jim's method will also result in a stripped pink cent, if it does manage to get the crud off.

Better would be a very long soak in olive oil using a toothpick to occasionally pick off the loosened softened crud. Expect this method to take six months to two years, change the olive oil from time to time.

Frankly why you would go to all that trouble for a corroded 1926 D or S cent is beyond me.

 

Instead of the pyrex dish, use a coffee mug, smaller piece of foil and start with a half teaspoon of soda.

 

All he has to do is put it on Ebay and put " possible SVDB" in the title and it's an instant $100 at the minimum !!

 

It actually looks to me more like a '20-D. Anyway, I was kinda more looking for the kind of advice I should follow, but thanks just the same for pointing out the kind I shouldn't follow.

 

It's already soaking. Couldn't stand the suspense of waiting.

 

Is there a way to get spots off of copper coins, or are they permanently ruined?

 

Depends on the nature of the "spots," I'd say. Beyond that, better coins through chemistry, understand, is always a quid pro quo. There's no "free lunch." As such, it's always a personal value judgment, whether to go forward. I'm out of place to say, in other words, you ought to do this, or ought to do that--that's your department, the "oughts." I'd suggest, therefore, just do what I did, show us a pic/scan of your coin...start there.
