2019 American Memorial Park Quarter-Ddr?

To expand on Jimmy's answer, this is incuse Machine Doubling. On incuse devices, Machine Doubling presents the way a doubled die would on raised design elements (enlarged devices, split serifs, etc.). On an actual doubled die, incuse design elements would be reduced, not enlarged.

So much to learn...thank you all! &

We are still finding new stuff all the time. So it will continue to add new things as we discover how these designs advance to newer designs/die processes/striking processes and what new things will be introduced.


New reverse frosting on the dies:
Normal not enhanced:
What is different? The fields are frosted and the design is shiny.

Reverse Enhanced Frosting:

Reverse frosted, with parts of the design enhanced.

With the laser, they can change the frosting on the dies. Before they frost the hole die, and then polish the fields to make just the fields shiny. But now, they can reverse frost these proof coins. So keeping an open mind, maybe we can find something new, even on proof coins. I remember one design that was not fully frosted once, but looks like I didn't save those images. (Or haven't found them yet?) But that is how we learn. Noticing slight differences on coins. Then later figure out what happened. So we are always learning new stuff.
