Lincoln Cent Error Help Please.

I went to an auction the other day and picked up a lot that contained 15 error cents. Most are clipped or lamination errors, but there were 3 that I need help with. First one is a 1977-D that was labeled wrong metal. It is silver in color and sounds like a nickel when it is accidentally dropped
Anyone know what this may be? Same size as a regular cent and I do not own a scale.


These 2 were labeled as "Dime Size Planchet" They are both paper thin and about the size of a dime


This last one was labeled "whisker cent" Looks like PMD to me, but those 3 main ones in front of Lincolns head are raised?

The rest that I see is junk. The 1951 and 1952 are classic acid jobs. The 1932 is heavily damaged.

I can see some copper peeking through at 2 o' clock on the obverse, and the plating is bubbling on the rims...

The clips look real, how can you tell a fake clip? Not that it means anything, but this was an estate auction and not a regular coin auction.
Here are 2 of the clips.
