What type of cleaning agent was used here(if any)

[jesbroken]

These two coins appear to have either been stored or in contact with a similar cleaning agent. Or is this a type of normal appearance that I've just not seen before. Any ideas.

Thanks

My 1860 has a similar look. I was thinking maybe it was the Copper-Nickel metal

Both coins look typical to me.

You both are probably right. I just have never seen this look, my 1859, 1862 and 1863 look nothing like this-especially the texture look. Just curious. Thanks to you both---Jim

They look dull and porous which is why I suggested they may be metal detector finds. Or it may just be the pics.

While the pictures aren't clear enough to determine what other surface problems may be present, the grainy texture and tan color are very typical of early Indian Cents and are not indicative of chemical treatment.

Thanks Perry, I just assumed the porous look was due to an abrasive substance but i stand corrected. Thanks all.

I agree.

They don't look cleaned to me, but rather that they were in some sort of semi-corrosive atmosphere for some time (in the ground). I have certainly seen this look on IHC before.

The odd color and texture of early Indian Cents is caused by their copper-nickel alloy. In 1864, the more familiar bronze cents were produced for the first time. Large cents, on the other hand, were supposed to be 100% copper.
