I don't see anything worth more than a cent ps: if it's md that doesn't make it valuable over face value at all. md is really common, what your really looking for is ddo. or doubled dies.
the reason the letters are flat and wide is probably because they have been banging into other coins from years of use and this has pushed the letters down and flared then out wider.
The lack of details on the face (all the missing details of the hair, etc) is due to wear... I'm just seeing a heavily-circulated coin.
Why does the t in liberty an to a lesser extent lots of the other letters have a cup shape with the edges flared up and a line down the middle? I have lots of worn coins but I've never seen one wit the edges of the letters taller than the center..
Most Zinc coins are pretty ugly when they wear. Every once in a while I find one like this with almost a rainbow of color.
