31D's are very hard to find in high grade. I searched shows and shops for some 20 years to find this one.
Even if we agreed, next to your collection everybody else’s coins suck. That’s the good side of the tradeoff.
I want to add....I literally saw hundreds of 1931-S's in that time period. Nobody hoarded 31-D's - they are a much tougher coin IMO.
Fortunately or unfortunately, 34 is pretty much where my luster starts and ends... Most of you don't have my problem.
