Thanks, Coop and Condor1 for clarifying because I agree with everything you said. (Not my cent tho.) My apologies because I wasn't very clear.
I was trying to clarify for newer members who might not have picked up on the difference between cent stock and cent planchets at the mint. (They do have cent planchets on site, but not the "flat" stock.)
The mint didn't have any cent stock that could have gone through the rolling and cutting process to produce nickel planchets. And since the tops of peripheral details are not missing, this is definitely on a regular nickel-sized planchet.
ps. Jarden Zinc has a great video on their FB page (Dec. 2016 I think) showing the copper plating process and even the burnishing process for proof planchets.
Words of encouragement are one of the major food groups.
We need to consume them regularly to thrive and grow.
