Prior to the invention of refrigerated train cars, fresh lettuce wasn't available at any price in certain parts of the country outside of harvest season.

Great point, I wasn't thinking of that.
So, especially in the northern cities, maybe the lettuce:nails ratio held true.
That makes it feel like a trick question, though. I wonder what the situation looked like for hardy vegetables like potatoes, onions, corn, squash.
