AI Appraisal Estimate

This is a standard-sized (2.5" x 3.5") baseball card from the 1990 Score set, featuring Mike Henneman, a Relief Pitcher (RP) for the Detroit Tigers. The card is identifiable by its vibrant green border and yellow inner framing. The top left corner features the '90 Score' logo in a diagonal yellow banner. The bottom right includes the classic Detroit Tigers 'D' logo with a roaring tiger illustration. The card features a dynamic action photograph of Henneman in full delivery during a game, wearing a white home jersey and blue Detroit cap. The player's name and position are printed in a stylized blue and yellow font along the bottom. The card appears to be in a protective plastic top-loader and soft sleeve. From the image, the corners show some slight softening characteristic of the mass-produced card stock of the era, and the centering seems reasonably balanced. The '90 Score set is a staple of the 'junk wax' era, known for its high production volume and glossy front finish. The cardboard stock is relatively thin compared to modern premium cards. No significant creasing or surface staining is visible, though glare on the plastic sleeve obscures the finer surface details.

I have virtually examined this 1990 Score Mike Henneman #283 card. Based on the visual evidence, the card appears authentic to the period, featuring the signature vibrant green borders and gloss finish associated with the 1990 Score set. The card's condition is consistent with 'Near Mint' (NM 7) grade; while the centering is aesthetically balanced, there is visible softening on the bottom-left corner and minor edge chipping common in this high-ink production run. This card originates from the 'Junk Wax' era (approx. 1987-1994), characterized by extreme overproduction. Consequently, supply vastly exceeds collector demand. Mike Henneman was a solid All-Star reliever, but he does not command the 'Hall of Fame' premium required to make cards from this era valuable. Comparable sales for raw commons from this set typically settle at or below the $0.25 mark, often sold in bulk lots for pennies per card. The protective top-loader and sleeve currently protecting the card are likely worth more than the card itself. Please note that an image-based appraisal cannot verify paper stock density or detect subtle surface alterations/trims. A professional physical inspection would be required to rule out reproduction or to verify the absence of microscopic surface scratches. However, given the low market value, the cost of professional grading would far exceed the card's potential worth.
