State of Ohio Prepaid Sales Tax consumer receipt stamp

This item is a small, rectangular paper stamp printed in a multi-tone color scheme of green and orange on a light blue-grey background. The face of the stamp prominently features the numeral '15' inside circles in both the upper left and upper right corners, with the word 'CENTS' appearing beneath each. Centrally, it bears a circular seal with agricultural imagery and the text 'STATE OF OHIO' and 'PREPAID SALES TAX' in bold block lettering. The bottom portion specifies 'CONSUMERS RECEIPT'. In the left margin, there is a vertically oriented serial number 'CTU20213'. At the very bottom edge, fine print appears to read 'RESERVE LITHOGRAPH COMPANY'. The stamp appears to be a physical specimen of Ohio’s tax stamp system which was operational between the 1930s and early 1960s; its design is consistent with mid-20th-century philatelic and governmental printing. The item shows signs of wear, including a significant jagged tear along the top left edge and slight rounding of the corners, suggesting it was likely torn from a larger sheet as per its original functional purpose. The colors remain legible but show subtle aging consistent with vintage paper ephemera.

Based on the image provided, the item bears markings consistent with an Ohio 15-cent Prepaid Sales Tax consumer receipt stamp, likely dating from the mid-20th century. My estimate assumes the item corresponds to common revenue stamps produced by the Reserve Lithograph Company for the State of Ohio. While the design and serial number CTU20213 appear representative of the period, I cannot verify the substrate or chemical composition of the paper via a photograph, which would be necessary to rule out modern digital reproductions. The condition of the item is a significant factor in this valuation; I observe a jagged tear in the upper left corner and moderate edge wear. In the market for revenue philately, condition is paramount, and such visible damage typically places a specimen at the lower end of the value spectrum. General market demand for common mid-century state tax receipts is relatively stable but low, as these were produced in massive quantities. If this item were found to be a reproduction or a common facsimile rather than a period-correct revenue stamp, it would possess negligible monetary value. To confirm the nature of this piece, an in-person physical inspection by a specialist in revenue stamps would be required to evaluate the printing method and paper fibers. Historical provenance or presence in a larger, documented collection could also assist in establishing its history, though its market value would remain modest due to the high surviving volume of this specific denomination and series.
