This is jut a quick way to eliminate 1793, 1795 and 1796 as possibilities in identifying Liberty Cap Large Cents without even looking at the Obverse or Edge or weighing the coin. Look at the M of AMERICA. It is narrower than those of all the other years and a few other 1794s with the wide M. This is true on 30 of the 41 reverses of 1794. So if you sse this small M, you know it's a 1794.
