Sharing some Lincoln cents errors

Ppp

I struck out on my post for a missing clad layer but I think I did pretty good with these recent I pick ups.

-1992 Lincoln cent, multiple struck
-copper (3.01gms) memorial cent: the right side of the obverse has impression of Lincoln and the date 195-, the left side of obverse has an impression of the Lincoln memorial. Unfortunately, I am having trouble taking decent pictures. What is this error called?
-1939 Lincoln cent, error name?
-1948 Lincoln cent, clipped planchet
-1974 Lincoln cent, cud

AMRC

What do you think the 1939 error is?

AMRC: fair question. I asked because I am confused. the reverse (see picture which I should have originally included) is slightly concave. Part of me thought die cap, then I thought grease filled die, then I thought pmd, so as you can see I am confused and I figure as always someone on this forum will straighten me out. 🙂

Part of you has the correct answer!
