NGC Slabbed 1943 P Nickel Die Cracks And More

This one recently travelled across the Atlantic to the UK, and on examining it with my lighted loup,e I noticed the following:



1. A die crack across the building from top to bottom, above the E in Monticello;

2. Another smaller die crack between the right-hand edge of the building and the rim;

3. A third mark above the final L in Monticello (not sure what this is, it looks a bit like a scratch).

Does this look like a known variety?

Thanks
