Circulated Fine-Vf 1955 P DDO? Or Something Else

Not seeing a DDO at all http://www.varietyvista.com/01a%20L...5PDDO010.htm

There are several different types of thickening on doubled dies. But the ones on the 1941 dies that had an issue with a class 7 doubled die:

But on the 1955 cent dies they were way over used. The is the strongest DDO that year: (Die 1) Also die 002 is also interesting as it looks like die wear, but is a DDO:

But like your coin, they pretty much looked lie that. Contact marks will flatten the devices and alter the shape. There also an issue because of the excessive usage, that altered the devices towards the rim area:

They will appear like this. But as the die ages that last 54% of the dies coins will show this extreme die wear, so they are common.

Thanks @Coinhunter27, the photos were taken using a system Ray built. Great system!

Also, can anyone take a moment and look at the G in IGWT, and help me understand how the upper part of the G looks like it was split, there is no shelfing. Is this wear on top of PMD?

Thanks John1!
