Even though it is circulated, it will help others to see better what does a circulated example looks like. These are teaching aids to help new ones spot what to look for when searching coins.
BU example:
_BAA.jpg)
_BAB.jpg)
_BAC.jpg)
_BAD.jpg)
Viewing the BU examples show the full
DDO, but the circulation alters the spread lines on the tops of the devices. So with two examples, you can see what could be there, or how to identify it without the spread lines on the tops of the devices. The more you are aware of, the eyes will learn to look in those areas. If not there, move on to the next coins. (don;t look at the outside edges of the devices as that is where
Machine Doubling lives.
Note again on image #3 of TB's images, note that the spread is not on the outside of the devices. But between the spreads of the devices.
