Below grade 10 the guide publishes one estimate across all graders, so these rows are not PSA, BGS, CGC or SGC prices, and a low slabbed grade can sit below a clean raw copy. Grade 10 is estimated per grader.

SuperCatch Expert Analysis

Market Value Insight

As a 1991 Upper Deck rookie card, this item sits within the entry-level tier of NFL football collectibles, reflecting the broader market dynamics of early 90s football releases. While the current price point indicates accessible liquidity, the presence of only one active listing suggests a tight immediate supply that could support modest price stability. Its value is anchored by its status as a first-year card, though it trades below premium vintage benchmarks due to the high volume of similar products from that era.

Rarity Breakdown

The primary scarcity driver for this card is its designation as a rookie card, which inherently limits the relevant supply to those issued in first-year sets. Being part of the 1991 Upper Deck base set means it is not a short-printed parallel or serial-numbered variant, relying instead on the natural attrition of a mass-produced base card over three decades. This lack of specialized scarcity attributes means its rarity is defined by condition survival rather than original production limits.

Investment Outlook

The rookie-card mechanic provides a foundational demand driver, as collectors often seek first-year appearances to complete basic set foundations or build starter collections. However, the absence of unique parallels or low-number serializations limits its potential for significant appreciation beyond general market trends. Long-term value retention will depend on sustained interest in Dallas Cowboys memorabilia and the general health of the vintage football market rather than intrinsic card rarity.
