That is a very nice looking coin, congrats on a nice addition with that 40 - S half in 67+ CAC
Actually the closing price for that 40 - D Lincoln was very cheap, most that I have seen offered for sale on dealer websites have been closer to $1,200-$1,400. That is why I have said that getting a 40 - D in 67+ is currently not worth the cost, too much money for the low points it receives in the registry. If you check the possible scores even a top pop MS68 (only 1 at NGC and 4 at PCGS) receives only 100 more points than one graded as MS67, it's crazy really. I suppose if I found one that was a real screamer I might someday consider upgrading if the price was right, but I can think of lots of other coins I would prefer to spend a grand+ on than this coin.
But rest assured I am not sitting on my laurels.
