I have a '77 Bally Evil Knievel EM Pinball machine (IPD No. 793) and am thinking of selling it. I have had it since the mid-80s and have always kept it in good working order. There are a few dings on the cabinet corners after many moves, but the playing fields, glass, art, etc all look good. I have seen several digital versions around for sale, but since there were only 155 of the EMs, I can't find comparable sales.
Any ideas on what the EM version is worth?
