I don't think you should do duplicates. The bottom one looks awesome except for the spot on the coat- stronger toned area, not really a spot. The middle one has the most full steps, but can't tell exactly from the photos. Go with the one you like and is most collectable both and finish other sets. Sell duplicates and use the money for one of your 10 sets??
I have a similar problem with high grade 1924-D's, and many of the real difficult ones......I end up keeping the best 3 or so in my personal collection and have no issues about duplicates, as I know they are tough and tougher. Throw them back in the safe Paul and think about it for a while.
you must have a few rolls of them by now? i have a few 24D as well never even imagined i would even one life sure is fun
