Why are people refered to as tin horns?

A tinhorn is "a petty braggart who pretends to be rich and important."





Supposedly it comes from "the horn-shaped metal can used by chuck-a-luck operators for shaking the dice."





And, in case you were wondering, chuck-a-luck is "a gambling game in which players bet on the possible combinations of three thrown dice."

Why are people refered to as tin horns?
A brief search for the phrase "tin horns" plus definition showed a high frequency of the phrase in the definition to callithumpian:





A somewhat riotous parade, accompanied with the blowing of tin horns.





There is also a musical band or group called "The Tin Horns," which seem to have made their way to public notice around this year.





I'll be watching this thread for other anwers. I thought there was a use for the phrase to indicate country bumpkins, local yokels, but I don't think that's right. Maybe those who can't make good music, thus they are "tin horns," or unskilled amateurs.
Reply:I thought that the idiom was "Green horns",
