factory grips - probably from the 70's / 80's - minimal value, $25+ maybe on ebay..
look like all are k-frame, square-butt grip frame
the ones with the rounded bottom are PC - plain clothes grips, supposed to 'show' less. they might bring another $10...
the last large pair in the link are target grips - probably 70's with the smaller football cutout go a bit more, maybe $50+
