2019 Shield Cent DDO On Liberty?

Thanks E&V. Nothing is listed on Wexler's site yet.

Interesting. I've never heard of high bounce md.

It is Machine Doubling on both areas. Note the areas affected are always reduced, thus a MD example.

The '9' on the date looks enlarged on all cents that year.

But is there any specific meaning for "high bounce"?

Sometimes you see Machine Doubling that affects the bases of the devices:

Some up a bit more forming a step:

This one even shows push doubling, distorting the overall size of the outside devices.
Sometimes it bounces a bit higher about 1/2 way up on the devices:


Here is an example of a high bounce:

So what E&V is referring to is that after the strike, depending on how loose the machine is, it can bounce upwards after the strike to damage the devices up higher on them.

After a while when you find out how common they are, then you will spend them. Just look again at the coin to see what we are talking about. Remember that MD is flat, shelf like, reducing the size of the devices and common. On a doubled die, you see a spread that shouts. Look at me. Also the location of the spread is different than MD. Machine Doubling is on the outside edges of devices, a doubled die shows the spread in the centers of the devices:

Note the differences between the normal devices and the doubled dies on each of these images.





Hope this helps.
