AI Appraisal Estimate

This is a United States 4-cent postage stamp from the 'American Credo' series, specifically the Thomas Jefferson issue released in 1960. The stamp features a bi-color intaglio printing in gray and red on white paper. The design prominently displays a quote from Thomas Jefferson: 'I have sworn... Hostility against every form of TYRANNY over the mind of man,' accompanied by a facsimile of his signature and a red quill pen icon. To the right, the word 'Credo' is written in a stylized cursive font within a gray block. The physical margins show standard perforations (perf 11), which appear mostly intact, though some corner wear is visible. Notably, this specimen is a 'used' stamp, bearing a black ink wavy line machine cancellation that passes horizontally across the face, along with fragments of a circular postmark showing parts of the words 'CAMPAIGN' and 'GERMANY.' The surface shows minor aging and off-white toning consistent with mid-20th-century philatelic materials. The centering is slightly skewed toward the bottom-left, a common occurrence for this issue. Overall, it represents a mid-century effort by the U.S. Post Office Department to celebrate patriotic ideals through typography-heavy design.

I have examined the digital representation of the 1960 American Credo 4-Cent Thomas Jefferson stamp (Scott #1142). This stamp is a common issue from the post-war era, with over 120 million copies originally printed. My visual inspection confirms the stamp is in 'Used' condition with a standard machine cancellation and a secondary circular postmark. The centering is ‘Fine’ at best, showing a noticeable shift toward the bottom-left edge, which is typical for the 1960 Credo series perforations. The colors—gray and red—appear consistent with the era’s intaglio printing, showing no significant fading. From a market perspective, this item lacks the rarity required for high-value philatelic investment. Comparable specimens are routinely sold in bulk 'kiloware' or as part of beginner collection packets. Its value is primarily sentimental or historical rather than financial. The presence of corner wear and a heavy cancellation further limits its appeal to specialized collectors who typically seek Mint Never Hinged (MNH) examples or aesthetically pleasing ‘Socked-on-the-Nose’ cancellations. While the stamp appears authentic based on the typography, paper toning, and perforation characteristics, a definitive authentication would require a physical inspection to check for hidden thins, repairs, or gum disturbance on the reverse. To confirm its status as a genuine postal artifact, I would examine the paper under long-wave UV light and use a precision perforation gauge. However, given the extreme commonality of this issue, the cost of professional certification (such as from the APEX or Philatelic Foundation) would significantly exceed the actual market value of the stamp itself.
