AI Appraisal Estimate

This item is a 1939 'First Day of Issue' postal cover commemorating the 100th Anniversary of Baseball as the National Pastime. It is an off-white, standard-sized envelope featuring a printed cachet on the left side and a canceled postage stamp on the right. The cachet depicts a baseball player in mid-swing against a detailed baseball background, with the dates '1839' and '1939' flanking the player. Above the player, it reads 'COMMEMORATING the 100TH ANNIVERSARY of BASEBALL the national PASTIME'. Below, 'FIRST DAY OF ISSUE' is printed. The design is primarily black ink with a yellow highlight for the baseball, giving it a somewhat sepia-toned appearance with age. The postage stamp, a purple 3-cent United States Postage stamp, features a dynamic scene of baseball players on a field. It is postmarked 'COOPERSTOWN N.Y. JUN 12 9-AM 1939', which is the key 'First Day of Issue' cancellation detail. Handwritten in capital letters to the right of the cachet are the words '-FIRST DAY OF ISSUE-' underlined twice. The envelope is addressed to 'Mr. Lester Rizek, Jr. / 4923 Carmen Ave. / Chicago, Ill.' in what appears to be typed or neatly printed black ink. The envelope shows signs of handling commensurate with its age, including slight toning and minor creasing, especially around the edges and corners, but generally appears to be in good, well-preserved condition for a paper item from 1939. There are no significant tears, rips, or major stains visible. The cancellation is clear and legible, as is the stamp and cachet. This piece represents a significant historical artifact for both baseball and philatelic collectors, showcasing quality craftsmanship in its printing and design indicative of early 20th-century postal memorabilia.

I have thoroughly examined the provided image of the 1939 Baseball Centenary First Day Cover. Based on visual cues, the item appears authentic, consistent with known examples of this issue. The 'COOPERSTOWN N.Y. JUN 12 9-AM 1939' postmark, coupled with the commemorative cachet and stamp, strongly supports its First Day of Issue status. The handwritten '-FIRST DAY OF ISSUE-' reinforces this, though it's likely a collector's annotation rather than an official mark. From the image, the condition is good for its age. While there’s expected toning and minor creasing, typical for a paper item from 1939 that has been handled, there are no visible major tears or significant stains. The clarity of the cancellation, cachet, and address is excellent, which is a positive factor. This particular FDC is highly desirable due to its historical significance in both baseball and philately, marking the widely accepted centennial of baseball in Cooperstown. Comparable sales for well-preserved examples of this specific Cooperstown FDC typically range from $150 to $250. Factors impacting value include the crispness of the strike, the overall condition of the envelope (minimal creasing/toning), and the legibility of both the cachet and postmark. This item presents very well in these regards. It is important to note the limitations of image-based appraisal. While the visual evidence strongly suggests authenticity and the stated condition, a full in-person examination would allow for tactile inspection of paper quality, verification of any hidden flaws, and microscopic analysis of the ink and paper, which would be necessary for absolute authentication and to rule out any potential alterations or reproductions, though these are relatively rare for this specific FDC. Provenance documentation, such as a history of ownership, would also bolster its authenticity.
