It can be more than a few bucks if the jockey is setting up a nice trifecta.
Eg. Fred (second fav 5-1 you win, Joe (fourth fav 8-1) you come second, and Tom (third fav 6-1) you come third).
I witnessed a certain jockey at Belmont on quite a few occasions burn a top favourite out by either coming out of the gates like a 'bat out of hell' and leading all the way, only to get swamped in the last 100.
The other thing he would do, is be the very last one out and burn the horse out completely trying to catch up, and again fail to get a place.
It wasn't just my paranoid opinion because I also saw fellow punters abuse him back at the enclosure.
What would the above trifecta pay?
