AI Appraisal Estimate

This is a United States documentary revenue stamp, specifically a one-dollar denomination from the series issued between 1871 and 1872. The stamp features a central vignette of a female allegorical head, possibly representing Liberty or an ancient goddess, depicted in profile facing right. Her hair appears styled with a wreath or laurel crown, suggesting classical influence. The color of the stamp is predominantly green and black, with the background or shading of the portrait in black and the main frame and text in green, creating a two-tone effect. The oval frame surrounding the portrait is inscribed with 'UNITED STATES INTERNAL REVENUE' in an arched formation above, and 'DOCUMENTARY' below. At the bottom, a prominent '1 DOLLAR' is displayed, with the numeral '1' enclosed within an ornate shape and 'DOLLAR' written beneath in a blocky, uppercase typeface. The stamp exhibits a perforated edge on all four sides, typical for postage and revenue stamps of its era, indicating it was designed to be separated from a sheet. The overall condition appears to be relatively good, though the image quality makes it difficult to assess finer details of wear or potential damage. There are no obvious tears or significant creases visible. The printing seems clear and detailed, indicative of the quality standards for government-issued stamps of the period. The paper itself appears to be aged, with a slightly darkened, off-white or yellowish hue on the unprinted areas around the perforations. No specific maker's marks or signatures are discernable from the provided image, as these stamps were typically produced by the Bureau of Engraving and Printing.

Based on my visual examination of the provided image, this is a United States Documentary Revenue Stamp, One Dollar, Series of 1871-1872 (Scott R103). The central vignette of a female allegorical head and the '1 DOLLAR' denomination with 'UNITED STATES INTERNAL REVENUE' and 'DOCUMENTARY' text are consistent with this issue. The green and black color scheme is also correct for this specific stamp. Overall, the condition appears good for its age. The perforations seem intact on all four sides, and I don't observe any obvious tears, significant creases, or heavy staining from the image quality. The printing appears clear, and the centering seems reasonable, though not exceptional. This stamp is generally considered common for the series. Demand is moderate, primarily from U.S. revenue stamp collectors. While a used example with a clear cancel could fetch a higher price, this stamp appears unused, which can sometimes command a premium if it's well-centered and fault-free. However, many unused examples exist. Market comparables for R103 in fine to very fine unused condition typically range from $25 to $75. Factors influencing value include centering, gum condition (which cannot be assessed from an image), and the presence of any hidden faults or repairs. It's crucial to acknowledge the limitations of appraising from an image alone. Authenticity, especially regarding gum and potential repairs, cannot be definitively confirmed without a physical in-person examination. For full authentication and a precise valuation, I would require a physical inspection to check for original gum, hinge remnants, thinning, creases not visible in the image, or any alterations. Scientific testing is generally not required for common revenue stamps unless specific anomalies are suspected.
