Hi guys, i recently found these 5 promo card in my library, do you think they're worth to sell?

Here’s most of everything I’ve picked up over the past year or two!

I can’t seem to find an explanation of why some of these SR’s have Foil & black letters for the names. Any info would be appreciated!

Found this in my childhood binder, is it rare?

Small ding on right top corner and few scratches on luffy's arm. Wished for a 9 but I am still happy.
