Baseball bearing multiple signatures in green ink

This item is a standard-sized baseball featuring a white, possibly synthetic, outer covering with red-and-blue and tan stitching. The surface displays multiple signatures applied in a green ink, which is stylistically consistent with green felt-tip markers or ballpoint pens common in the mid-to-late 20th century. Visible signatures include names that appear to read as 'Ken Reynolds', 'Terry Harmon', and 'Bucky Brandon', which may be consistent with several Major League Baseball players of the 1970s. The owner suggests this may be a 1972 Philadelphia Phillies team-signed ball; however, this claim is unverified at this time. The ball bears a small stamp at the top reading 'JAPAN', suggesting it may be a souvenir or practice-grade ball rather than an official league-issued game ball. The condition shows moderate yellowing or toning of the surface consistent with age, along with some slight scuffing and fading of the ink in certain areas. Because signatures can be printed, stamped, or forged, and because the ball itself lacks official league branding symbols, this attribution remains a hypothesis subject to in-person authentication and verification of the ink and handwriting against known exemplars.

Based on the provided imagery, the item appears to be a multi-signed baseball featuring signatures consistent with the 1972 Philadelphia Phillies roster, such as Ken Reynolds, Terry Harmon, and Bucky Brandon. Per user submission, the ball is identified as a 1972 team-signed item. However, I cannot verify from a photo if the signatures are hand-signed, stamped, or printed. The presence of a 'JAPAN' stamp suggests the ball is a souvenir-grade or novelty item rather than an official league-sanctioned game ball, which typically impacts market appeal for serious collectors. The green ink is stylistically consistent with late 20th-century markers, though the moderate toning and fading suggest significant age and potentially light exposure. The estimate of $50-$150 assumes the signatures are hand-signed and represent the hypothesized 1972 team. I must treat this attribution as a hypothesis; the value is entirely dependent on professional third-party authentication of the ink and handwriting against known exemplars. Without such verification, or if the signatures are determined to be facsimiles (stamped), the value would likely drop to a nominal range of $5-$15 as a vintage novelty item. To confirm the status of the item, an in-person physical inspection is required to analyze ink penetration and stroke pressure. The market for mid-tier 1970s team-signed balls is stable but sensitive to the 'Official League' status of the ball itself.
