Well, it just so happens that the only 1830 I currently own is one of the die marriages that Frank is missing...O-115. R-2 Obverse: Star 1 points to lower edge of dentil. There are numerous diagonal die lines below bust, from date to star 1. “3” is low. A raised elongated lump shows on neck, left of curl. Reverse: Upper tail feather pierces the olive stem, forming a tiny knob. “5” has an open loop, and a short straight V-shaped top. Stripes and crossbars are sharply struck, and the crossbars slant upwards to the right. Lines 1 & 2 of stripe 3, and line 2 of stripe 4, extend too far down. Left sides of “I” and “T” are in line.
