Snake skin in transclucent light

I believe I found this skin in or around Longleaf Pine habitat in Georgia. I am wondering if it came from an Eastern Coachwhip snake (Masticophis flagellum). I worked there as a wildlife biologist and I believe this species was probably the most common in the area.

If there is a herpetologist reading this and you can identify this snake, please let me know what species or genus this is.
