On this tangent is somewhat solved by between session "Vickrey auction". It's a sealed bid auction where the winner pays the second highest bid. The auction type encourages bidders to bid around the actual value and the gm can manage results somewhat with NPCs bidding above bids that aren't enough of a gold sink or bidding verrrry slightly below any absurd vids that are banking on paying a more reasonable second price. Doing it between sessions means PCs need to be in town end of season and the gm has time to mull it overI agree. Magic item pricing is difficult. The other problem with making magic items expensive is that if they find such items, they can sell them for a lot, which may have other unintended consequences. I'd be inclined to have legacy magic items or similar that scale with the characters in an appropriate manner, while being an iconic item or two for each player character.
There was a Traveller campaign where we managed to capture the enemy spaceship after they boarded us. Our conclusion was: sell it, then let's retire! The game master agreed with our logic.![]()
I don't think that kind of manipulation of the auction by the gm is unreasonable given that Ttrpg economy is so simplified and how players get to ignore anything they would feel a need to hold back over if they were the actual PC.
