Quoted from 1974DeltaQueen:

Gemeni to my knowledge is the highest priced EM, then Joker Poker & Mata Hari.
the crazy thing is I sold my Abra way too quickly. Had I waited That example would fetch near 2500 it was that nice! The market trend is for 3" flipper games 1975-79, ACD. C-37, Atlantis. Team one is a better game than ACD but the art mucks soose.
The decrepid people like me who prefer 2" flippers, we're a dying breed of baby boomers. And kids today can't relate to those games that require nudging and balls you can't trap.
