I don't think the WDDO-002 will be easily missed. If you look at them before magnification you will probably notice it. It is massively distorted. The 001, that one is a different story. There are also about 10 trail dies listed for the '14s.

I can empathize with that. Also, there is a die crack on the lower left of the reverse banner that sometimes extends out and to the rim to look for. I actually save all of the nicer die cracks and bundle them in lot's of 20 or 100 for resale on Ebay. They sell slowly but they do sell and it helps me recover some of my time and investment in these boxes. I have had a lot of positive feedback in private messages from coin club members and flea market folks who love these. They are a good learning tool for YN's who want or wish to study the die deterioration process.
