1971-D Kennedy Half Dollars With Possible Errors

Okay so my girl is the manager at a retail store & some kid came in and paid for his stuff with a stack of half dollars & all of them were 1971-D's. She knows how I am about coins & brought them home to me & I found it extremely odd. Not that the kid paid with them (obviously stole them from a parent) but odd that someone only collected this specific coin. So I started checking them out and all of them seem to have roughly the same things happening on them however according to Wexlers list the errors I might be seeing aren't listed but the list is also incomplete. So what's the opinion of the masses here. Is it just wishful thinking on my behalf & the original owners or are they legit unlisted errors? The double eyelid & the designers initials are the two common factors on all the coins. Oh & there were 8 coins but in total. The two photos of the eyelids are of different coins but they all look like this & same with the "FG". The ones on Wexlers list don't show these same flaws. So I came here to ask all of you before I spent them lol
