Postal Stationary -
Rate Comparison Chart of New York Covers traveling a distance of 150 to
during the years 1825 to 1845. The correct rate was 183/4
Two of the 1835 covers and one 1837 cover were marked incorrectly at 181/2
however earlier covers from 1826 and 1828 were marked correctly.
(I believe the Postal employee
just made a lazy marking and that the correct rates were charged)
