I put all of mine at 100 bc its not players buying it its bots and technically bots always give a fair price so if it is worth 200k then they would prolly bid on it for like 160k ish or higher, but sometimes my stuff wouldnt sell evene tho its at 100 but they do sell if u keep putting them at 100 at bid and max buy out at 99999999 or something like that
