Hi Imho, looks like a perfectly good penny. I’m sure an expert will be on here in a bit but in the meantime... here’s a little reading material on double die varieties. http://doubleddie.com/
Hi there, what your coin shows is machine doubling or strike doubling. It's detectable by the flat and shelf-like doubling you see when the die sort of slides across the planchet. It's not considered an error and has no added value. If you like it, keep it, but it won't get you any premium. http://www.error-ref.com/machine-doubling/
