Bill is right on all counts.
I cherried my example of the 1970S proof small/large date at a small local show in September 2006 in Tulsa, OK for a buck. It was in a PVC flip and had some haze, which I promptly removed. The coin is now happily resting in an archival flip in my collection. Its grade is PR66RD and I would venture a $125 value.
Your coin, however, is just a machine doubled large date cent.
