At the York stamp show I picked only one Scott #24. I was looking for curls as usual and found what I believe to have a plate scratch going thru the "N" of Cent and has a Mobile CDS. I wasn't looking for types but I think its a type Va. I haven't plated it yet but will try to later today. My Neiken book is getting dusty and needs reading anyway.
1st is the "plate scratch".

2nd is the the stamp itself.
