a little penny help

[TNdigginsafari]

I have found alot of severly coroded pennies in the middle of a large farm field that has been planted with various stuff for as long as i can remember. I assume there was a house out there at one time as I have found personal items also. Most all the stuff is coroded badly I guess from farm chemicals. Is there any thing I can try to get this severe corosion off?? I am thinking I may have a bunch of IH pennies but I cant make much of what I can see on them

Penny corrosion is usually one of two types. Sometimes it is still on the surface of the coin, and other times it has eaten into the coin itself. In Wisconsin, the Indian heads often come up green. Sometimes the green is simply a change of color and the details on the coin are very sharp including all of the feathers in the headdress. I don

Thanks looks like it may be hopeless because they do have a crusty green and white raised corrosion on them. I was not really wondering about value tho I was just trying to find out what they are exactly (wheats or indian heads)
