1861
The Union's blockade of Southern ports was successful to a point, but it was porous. On June 10, 1861 just below New Orleans, the CSS Sumter under the command of Captain Raphael Semmes, ran the Union blockade and began his career as a raider of Union cargo ships.
the 1861 Confederate penny was made of copper or nickel
During the first nine months of the US Civil War, the Union's blockade of Southern ports was not successful. In the year ending in 1861, nine out of ten ships eluded the Union's efforts. One reason was that the Northern navy simply needed more ships. Union shipyards were busy trying to fix that problem. Union shipyards had the great advantage of being geographically safe from harm. The Rebel army was just too far away.
Jefferson Davis was elected president of the confederate states in 1861
For the Confederacy, it can be argued that the most significant event for its fledgling navy took place on June 30, 1861. It was the date that the CSS Sumter ran the Union blockade on New Orleans. The ship's captain was Raphael Semmes. Captain Semmes thus began his career as a blockade runner and a Union commerce raider.

The likelihood of Britain and France intervening on the Confederate side.
The Confederate Constitution was enforced on March 11, 1861. The Confederacy also operated under a Provisional Constitution from February 8, 1861 to March 11, 1861.
On May 13, 1861, the British Proclamation of Neutrality was issued. Based on international law, this gave de facto recognition to the Confederate government, but of course there were no diplomatic ties based on this. France later issued a similar proclamation. To the British this meant that the Confederates had to abide by the treaty against privateering, while the Union had to construct an effective blockade. Also, later on the British, French and Spanish did not allow privateers from bringing in captured prizes to their ports. This effectively ended Confederate privateering as there were no ports in which to sell captured ships.
