The record is one line covering lettered edge and reeded edge together: 6,546,200. The trade splits it 6,545,000 lettered and 1,200 reeded, and the two sum exactly. This series ends inside a date, and the Mint drew the line itself — the first steam coinage in America on March 23, 1836, steam milling, and dies hubbed entire so as to make them “exact fac-similes of one another.” PCGS publishes no plain-date estimate; the 50/00 runs 600 / 20 / 2 at R-5.8.
