Akro Agate (and yes that's English)

The unearthing continues at my parents house and how I feel I've just found gold!  I came across a beautiful child's tea set stored with my mothers vintage dolls.  I have no recollection of them (translation - I wasn't allowed to play with them as a child) but my heart raced with excitement. Could this be love? A quick image search of brightly colored glass identified them as Akro Agate Depression Era Glass.  The colors are majestic and vivid and of course are highly coveted among collectors.  The question now is.......Do I sell or keep?  If I keep I'm having a tea party with all my mothers dolls this afternoon.
