Quoted from arcademojo:Just about any Williams system 3 & 4 games.
Pokerino does not go for much, but I worked on one a couple of years ago, and was pleasantly surprised by its gameplay. It was kind of like a widebody Joker Poker.
As far as lowest value games add GTB Dragon or Torch, Bally Freedom, Williams Millionaire (as far as Sys11s go), Atari Space Riders, and Stern Stingray. Also, most any soccer themed game goes for less than anything else.
