Rejuvenation...

Serpents, as they grow, eventually become to large for their skin. During an event called Molting, the snake rubs its head against a rock or piece of wood causing their already Too Tight skin to split. As the snake continues to rub its skin on rough objects it causes the end nearest the head to peel back on itself, until the snake is able to crawl out of its skin, turning the moulted skin inside out. Kind of like peeling a sock off your foot and turning it inside out in the process. Often the discarded skin can be found in one piece.

This Skin is probably from a Black Racer, a Snake native to our area here in North Central Florida. It is non-poisonous and very commonly found in the Eastern U.S. They can grow rather large, it's not uncommon to see them up to 60 inches (152 cm).

Personally, I believe spotting a Serpent in the Wild is a Sign of Very Good Luck!
