costume jewelry -- clip on earrings (group 1)

A little while back I showed a trayful of assorted costume jewelry I came across recently -- now I'm finally getting around to sorting thru it all and discovering what's all actually there. Here's the 1st group of clip on/screwback earrings. They are a miscellany of all sorts of beads and baubles, none likely too terribly valuable but perhaps "unique" nowadays, as chances are all this stuff was first collected numerous decades ago by somebody's grandmother -- whoever she might have been she *did* have some fun things in her jewelry box!

First pic shows the fronts, 2nd shows the means of attachment to the ears, 3rd & 4th are closer shots of the group.

COMMENTS WELCOMED PLEASE -- especially if any of y'all jewelry experts recognize something about anything that I'm overlooking -- I don't really know squat about such stuff -- or even if you just have a favorite or three -- I'll gladly add more details or another showing if anybody wants to see something better!! ;-) :-) :-)
