Have some title examples?

Some machines have had code updates, various media exposure (including inclusion in popular virtual pinballs), themes have come around, players have discovered the machine etc.

Also looking for confirmed sales, not just weird asks on classifieds.

Can't say I've seen demand at all for Rescue911 or LW3 in my region.. they just sit. certainly, there is a price, where just the feature of having a DMD demands some kind of value threshold for many.

Some Sega titles, Baywatch etc.. certainly do seem to be on the radar of more buyers lately.

I find these are all so subjective tho. At times, there are people who will really want something like Rescue 911 because the service theme is important to them.... so if you happen to list high, at that time.. sure, you probably have a sale. At the same time, is your average pinball buyer going to snap it up? no.. it will likely sit for some time, until the right buyer comes along, or if the price is low enough for someone to just snap it up.

This pretty much defines the C tier machines if you will..

IDK.. so many factors with pricing... not sure if any hard values can be said about the handful of TFTC the come up for sale.. Some DE titles have great licenses which will always have some desirability.. does not mean they will be a 5k insta-sell.. but for sure, if someone wants that theme, and the transportation of the machine is within their means.. then sure.

I think OP is thinking of particular titles.

Not sure if Baywatch was ever particularly 'not' desirable?.. maybe before my time.. Rescue and LW3 I've never known and still do not see them command high list values...

Maybe in your region you had a surplus floating around... It has always been in demand around me in bc, Canada... One of the more nostalgic pins people look for I have found... also just a really great player. Rules are quite conducive for competition.

Eight ball, the fonz pin.. .. More synonymous with happy days than nip it. Lol.
