Quoted from dung:

If you did it solely off averages per pinside 1200 cash to him plus amh.
BK Prem is falling in value if you look at the last few sales. Newer games tend to do that unless they are out of production and highly sought after. This could change if it got a major code update that radically improved its standings, but otherwise it will continue to go down in value for a bit before leveling out. Right now this seems to be in the low 6's , but with people dumping for Avengers listing it at 62-6400 would probably have it sitting for a bit. (assuming no major mods and huo here).
AMH would depend on what it has. 150 made and if someone is wanting one they will pony up, but it can also end up sitting waiting for a buyer. Pinside values are handy if a game is stable/unchanged, but since they are historical major changes that affect value are not factored in. Major code updates that change perception of the game, major mods, sudden upticks in interest (this used to happen when streamers would feature games, radical is a good example), etc. In AMH's case sales history does not reflect the color display addition or the sound upgrade. Last sale had it but they listed low, even compared to the prior several sales. HUO, fully decked out game would probably hit 6k+ especially heading into the christmas selling season which includes october.
That all said, if I were Crile1 I wouldn't do an even trade for an amh. Would be better off selling it, being patient and waiting for someone to list, although given the rarity if he has to do shipping it could cost more, so its waiting for one within driving distance. As an AMH owner I wouldn't do an even trade unless I really wanted a bk prem. Long term it will go down in value. I don't see amh radically climbing unless it becomes a flavor of the month, but it will hold its value and average prices will probably creep closer to 6k with the current mods available. Just my opinion.
