Numerals Cinderella Stamp
Most stamps bear numerals of some sort that indicate their value as postage. The First two U.S. stamps featured an Arabic "5" on the five-cent issue and aRoman "X" on the ten-cent issue. The denomination may be shown as a numeral, or spelled out, or even both. Some recent stamps show no numerals at all, but are valid for the current rate for their level of service.
