Last year I had picked up two 1787 Fugio Cents during an afternoon hunt and put them away until I could get to clean them up a bit. I finally got to them today. Both had thick crusted-on verdigris on the obverse side, making it difficult to clean and remove. The reverse of the coins held up better, though one of Fugios does have a break at the top, apparently resulting from someone's attempt to make a hole.
Here are a few photos of the Fugios after the cleaning. Now I just need to identify the varieties.
