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 11. 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. If you are a new member and wish the DVD, make your donation and have them pass on to me where you would like this shipped. Most have really appreciated this to increase the coin knowledge. Thanks for your support!
