It is in a PCGS 65 holder however the variety is not listed on the slab. I believe it is a large date but cannot discern whether it is copper or zinc. My intuition tells me it is zinc as there appears to be some bubbling that is notorious on the early date zincs.
Can anyone tell what this one is:

these early dates seem to have plating issues and this applies to some later
dates as well.

I also agree...and yes it is a large date.
