Dug this one near a basketball court this morning and no clue what it is. Did nothing but brush it so far. Looks like a face looking left, possibly a K with other letters up top. Barely larger and thinner than a LC. Just a toasted LC?

Hi!
Try to grate some laundry soap and mix it with water.
Then put the coin to this substance for a week or two.
Then clean it with water only and may be it helps
I use this method with old copper.
Safe method
