Quoted from DB62:Look at :
1954 Genco two player basketball
1955 United deluxe super slugger (pitch & bat)
Many EM manakin games
While I'm not disagreeing with you regarding these particular machines, we're on a pinball forum and every EM game you presented as an example of higher dollar EM games isn't a pinball machine...
I agree that there are some higher dollar EM pinball machines and ultimately, condition and title determine value. I think it's safe to say though that in general, EM pinball machines are at the lower end of the spectrum when it comes to cost - and I'm cool with that.
