I think that there may be a relatively simple way to follow the price trends in used pinballs.
If it were possible to create a very basic schedule of Addams Family prices over time, I think that this would act as a fairly accurate proxy for the market as a whole.
I suspect that strong correlations with other games will exist. Ie a Fish Tales might be 0.5x an Addams, a Whitewater is maybe 0.7x an Addams, a TZ 0.9x an Addams, a Med Madness is 1.2x an Addams for example.
Why Addams ? The most common pinball machine. Mature market (no depreciation). Best price data you will have on any pinball machine.
Back in the 1990s I was a UK govt bond trader. This was a horribly illiquid market, offering poor price transparency, with dozens of rarely traded securities. What was actively traded however, with excellent price transparency was the 10 year LIFFE future. This was the canary in the coal mine that you could follow and the market basically priced the other securities off this one.
Of course this was then nuanced for bond duration, tax effects. High coupons v low coupons. Tap issues .... but the simplistic model worked.
It would be the same for pinballs - condition, remakes, projects ...
