1861-S $20 Paquet XF40 PCGS....

--Lettering and mintmark. The letters are tall and thin on the Paquet Reverse, with virtually no space inside the enclosed letters: A, E, O, R, D. In particular, the enclosed area inside the O(F) is almost a straight line on the Paquet, while it is nearly round on the Normal Reverse. No period follows TWENTY D on the Paquet Reverse, but a prominent period appears on the Normal Reverse. Because the letters are taller, the S mintmark is smaller on the Paquet, squeezed vertically between the denomination and the eagle's tail, and horizontally between NT of TWENTY. There is a much-wider space between TWENTY and D on the Paquet.

--Glory of stars and rays. The glory of stars intermingles with the rays descending from above on the Normal Reverse. The Paquet Reverse positions the glory lower, with the rays distinctly above it.

--Other design elements. Although many of Paquet's changes to the central reverse design elements are quite subtle, several are noticeable when the two issues are compared side-by-side. The eagle's head is larger on the Paquet. There is more space (and more of a circular space) in the recess outlined by the underside of the neck and the vine the eagle holds in its beak. The terminal volutes on the vines and ornaments are elongated and less rounded on the Paquet. Those at the left and right outsides end below the U and A in UNITED STATES OF AMERICA, while their counterparts on the Normal Reverse end under those letters.
