Just arrived, 1901 10c NGC PR64, Reverse 3 (thick ribbon). The end of a collecting era for me, as this was the last of 21 Barber dime hub transition varieties I've slowly been acquiring. Very glossy reflective appearance. Its sibling, 1901 10c PCGS PR63, Reverse 2 (thin ribbon). Picked up a little over a year ago but I don't think I ever posted it here.
It may be the lighting in the photo, but the one on top looks awesome, the bottom one not as good. I do not not know one thing about any of the Barber series of any the denominations. I try to keep my ignorance contained to Morgan Dollars.
These are the only proof coins I own aside from a 1971-S Ike, so I know very little about them either. Both are rather dark with age, and thus difficult to photograph. Originally I didn't intend to get the proof anomalies but once I went down the rat hole I had to finish it. Because the mint switched to the newer Reverse 3 for the June and subsequent September and December proof deliveries (presumably, based on research), I'm suspecting the glossy one was from fresher dies or they did something different with them. You can see that the obverse dies were different based on the date position. Their appearance is more similar in the seller images, below.
I still say your one on top is way nicer than the one below it. Just based on my raw eye appeal. I see a lot of stuff online that is graded and still can't comprehend how graders based their opinions on. I generally hate toned coins unless it is lightly toned, enhances the look and doesn't take away from a coin's luster. Yet everyone has different tastes, so the world goes. I don't know enough about Barber dimes to even know what value you have going on here. It's okay, I am quite sure my posts of interest bore 95% of the membership here.
And my posts bore 99%. You want to talk about comprehending graders, look at proof Barber dimes. How they decide the difference between PR64 and PR67 is beyond the grasp of mortal men.
Would you say there is date doubling underneath the 188 or lighting shadows? I have a hard time telling the difference.
