It appears that it is a result of a Machine Doubling but due to the condition of the Mint Mark, it may have been Ejection Doubling or both. Note the shadow doubling on the bottoms of the lettering in "FIVE CENTS". Not sure if a pic of the entire Reverse of the coin would help with assessment but it might.
By the way, welcome to TNET and hope you will tarry with us and share more finds and any stories of finds!
Thank you for the reply. Should I get this coin graded then as a form of error or just as it is a good condition 1934-D. Also,here is the images of the rest of the reverse.
I will also try to post a bit more as I do a little bit of both roll hunting and metal detecting,Thanks as always!
Not a RPM. The lower part of the D is machine doubling/shadow doubling as Huntsman called it. The upper part of the D appears to be from a post mintage strike by something, thus PMD.
While not valuable, it is a good find and takes a keen eye and a good gem loupe to find such doubling and other things on coins that should not be there. It is a learning experience when it comes to Error and Variety coins and you are on the right path. You just need to study up on Errors and Varieties and hone your skills. Good luck!
