I still check Denver coins. You might just find the first example. That is how I found the first 2002-D DDR
I knew the 2004's had the EPU doubled, So I checked all years of the Zincolns for the doubling in that area. It paid off. I think there are about 4-5 examples known by me of this die so far. A lot more out there that are missed.

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 9. 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.
