In OTL, Lysander Spooner fought the US Government's legal monopoly on mail by establishing a private mail company. The 3 cent stamp is his legacy. Unfortunately, he was financially ruined by legal proceedings before he could get the case to the supreme court.
What if he had managed to take it to the SCOTUS and convince the Court to rule that legal monopoly was unconstitutional? It would be in the decade before the Civil War that this would happen.
