I definitely started with my games set on coin play but after awhile I converted to free play. All but one still "coin up" so sometimes I leave coins out for parties.

Reminds me of my 1960 Vendo Coke Machine. Started to look for a coin mechanism (did not come with one), but quickly realized that I got enough sensory satisfaction from the sound of the bottle being pulled out of the machine, others rolling down behind it, etc. Same thing for the EM's - I like the sound of the coin mechanism, but it's really the sound of the score reels and relay banks resetting that gets me excited.
