Hi Anthony,

Thank you for contacting Mearto with your appraisal inquiry.
Ungraded stamps are given a fairly broad value range, which can usually be narrowed by having the stamp professionally graded. However, based on the number of perforations and the black markings across the face suggest this was one of a very large production run with very modest value
Based on the photos and information provided, and subject to examination, this is:

A Benjamin Franklin green one-cent stamp
1923
with 12 perforations
CONDITION: marked (cancelled?) across the front
$5-500*
*represents a fair-market value for auction purposes; retail or asking price may vary.
