Metallurgical testing conducted by Professional Coin Grading Service on two 1792 cent patterns has determined both to be composed of virtually pure copper and not a fusible alloy of copper and silver.
Currently, no purported 1792 Fusible Alloy cent patterns have been metallurgically confirmed to contain silver, although U.S. Mint records cite its use in their manufacture.
The analysis of the two pattern cent coins currently in the hands of separate collectors brings the total number of examples of the Judd 2 pattern cent in virtually pure copper to three.

The only previously confirmed example in virtually pure copper is in Good condition and housed in the Edward C. Rochette Money Museum at the American Numismatic Association headquarters in Colorado Springs, Colo.
The Judd 2 pattern was executed by U.S. Mint engraver Henry Voight, who is also credited with creating the 1793 Flowing Hair, Chain cent and 1793 Flowing Hair, Wreath cent.
The same dies used to strike the Judd 2 variety also struck the Judd 1 Silver Center cent patterns.

The Silver Center cent patterns were struck on copper planchets with silver plugs inserted into holes pierced into the center.
The Fusible Alloy cent’s composition was supposed to have been comprised of a small amount of silver added to the copper in a homogeneous (that is, fusible) alloy, from which planchets were then fabricated.
