One more... for now. At first I thought this was a mint mark match for VAM-4, but I now see that there are a LOT of Micro O varieties for 1880-O, and this is not the 1880/79 overdate. Upon closer inspection, this one appears to match VAM-74 (Doubled 880 / O tilted right). Others markers match as well. Just want to make sure this is correctly attributed so I can include it in my final image. Thanks! @Dave Waterstraat @rmpsrpms.
Just realized that I didn’t tag @messydesk in this and my other post. I was thinking of him when I tagged Ray. Not sure how I confused their handles.
