1957 D LWC. Is This PMD?

I was actually going to comment on the L, because I saw that too.
Die crack causing the raised line to the L.
The B filled in Liberty is cause by a die chip, there was actually a lot in the 50s. They are still cool to find. Another big one in the 50s is the "BIE" which is a die chip that causes and extra piece in the shape of an "I" in between the B and E in Liberty.

The incuse marks on the surface are circulation damage. On LIBERTY you see a lot of circulation flattening on those devices. On the 'B' in Liberty you are seeing the bottom of the 'B' as filed. This is not a grease issue. The post that forms the center of the 'B' has broken off the die and now just leaves the void filled on the coin.


The post gives definition of the centers of the various letters. 'B, O, 6, 8, 9, 0, ETC. This is also the result of extreme die wear. Thus we see various dies of the 1950's wheat cents showing a lot of issues because the mint continued to use the dies way past normal retirement. We see the heavy die wear, die cracks, chips, breaks, Retained Cuds and finally a Cud that forces retirement of the die.
