This type falls under the common index of the common single arc units, but it is anything but the same. These have a unique profile, as well as crudely engraved lettering, which in this case includes a backwards "N" in the "N. Y.". Note the very wide space between the two letters peculiar to this style. This one has a few pecks and scrapes from use, but no real chips or whacks to speak of. A crudely cut "13" with a backward "1" adorns the reverse crown. A hard to find CREB pony. $20 + shipping.
