When a is killed, a large floating silver coin icon appears above their point of death. As long as this coin remains in the world, the trader will respawn after a random amount of time, which can be anything from a few minutes to over an hour. If there is not enough room for a trader to spawn, the coin will gradually rise up through any obstacles in its way, guaranteeing an eventual respawn. This is very useful on multiplayer servers with players who would love to give others a hard time by killing traders near their base.
