The "Y" tends to be taller on this year. A heavy die polishing can thin the devices. So I think this common for the year.
Note LIBERTY in this image:
I know it is a doubled die on these images, but you can see the "Y" towering over the rest of the devices in that area.

Some have asked about my images I use and I'm glad to say, I've completed an Educational DVD of these. Become a supporter of this site, send me your address and I will send you a DVD. Many have loved this so far. I just completed version 10. The most updated version yet. So if you haven't got a copy yet, it is a good time to do so. I also have a DVD and one for windows media player. The one for media player is nice for your computer as it is clearer in images. Let me know which you would prefer.
