Kon Knueppel 2025-26 Finest SuperFractor 1/1 Sold

2025-26 Topps Finest Electrifying Signatures SuperFractor #ESG-KK Kon Knueppel Signed Rookie Card (#1/1) – Market Notes on a Modern Superfractor

On May 1, 2026, Goldin closed a notable ultra-modern basketball sale: a 2025-26 Topps Finest Electrifying Signatures SuperFractor #ESG-KK Kon Knueppel Signed Rookie Card, serial-numbered 1/1, graded PSA NM 7 with a PSA/DNA GEM MT 10 autograph. The final price was $17,080.

For a still‑developing prospect, that’s an attention‑worthy result. Let’s walk through what this card is, why it matters to collectors, and how this sale fits into the broader market context.

Card overview and key details

Here’s how the card breaks down from a collector’s perspective:

• Player: Kon Knueppel
• Team: Early Finest branding typically pictures him in his first professional or featured uniform (check the card image for the exact team logo and colors).
• Year: 2025-26
• Set: Topps Finest – Electrifying Signatures insert
• Card number: #ESG-KK
• Parallel: SuperFractor (gold, 1-of-1 finish)
• Serial numbering: Stamped 1/1 on the card
• Rookie status: A signed rookie card from his first Topps Finest appearance
• Autograph: On-card signature, authenticated and graded by PSA/DNA
• Grading:
  • Card: PSA NM 7 (Near Mint)
  • Autograph: PSA/DNA GEM MT 10

“SuperFractor” is Topps’ signature 1-of-1 parallel—there is only one copy of this exact card. For many collectors, the player’s SuperFractor rookie auto is considered the top-end, non‑memorabilia card from a brand like Finest or Chrome.

Why this card matters to collectors

1. SuperFractor + rookie + on‑card auto

When collectors talk about a player’s “true top” cards in modern chrome-style products, they usually mean:

• The 1/1 SuperFractor (or equivalent top parallel)
• A rookie-year card
• Preferably with an on-card autograph

This Kon Knueppel card checks all three of those boxes. Regardless of grade, there’s only one person who can own this exact SuperFractor auto. That scarcity is a large part of the appeal.

2. Topps Finest in the ultra-modern era

Topps Finest has been a long-running chrome brand across sports. In the ultra-modern era (roughly mid‑2010s onward), Finest has settled into a role that collectors often view as:

• More niche than the absolute “flagship” Topps or Prism/Chrome releases
• Still very respected for its parallels, refractors, and on-card autos

Within Finest, an Electrifying Signatures SuperFractor is near the top of the ladder for any player. When that player is in their rookie season, it naturally draws extra attention.

3. Prospect and hype cycle dynamics

For prospects and young players like Kon Knueppel, prices often reflect:

• Pre‑debut hype, draft position, or college performance
• Early professional flashes (if applicable)
• Broader optimism about upside rather than proven accomplishments

Ultra-modern 1/1s can move quickly on both positive and negative news. That doesn’t mean this sale predicts anything; it simply shows what one well‑informed buyer was willing to pay for the only copy at a particular point in time.

Market context and recent sales

Comps and scarcity

“Comps” is hobby shorthand for comparable recent sales. For a 1/1 SuperFractor rookie auto, true comps are usually:

• Other Kon Knueppel 1/1s from different brands (e.g., similar chromium sets), or
• Lower-tier but numbered parallels from the same set (like Gold /50, Orange /25, Red /5) to triangulate demand.

Because this specific card is a one-of-one, it doesn’t have direct, repeatable auction history. Instead, collectors look at:

• How his other numbered autos are selling
• How similar SuperFractor autos for comparable prospects have sold
• The gap between this sale and those other results

As of this writing, public data for this exact card is limited to isolated appearances like this Goldin auction. Comparable Kon Knueppel Finest autos in lower-numbered parallels have been trading at significantly lower price points (often in the hundreds to low thousands depending on color and grade), which makes sense given the massive scarcity jump from, say, /50 or /25 to a 1/1.

Given that context, $17,080 lands in what you’d expect for a single, premier 1/1 rookie auto of a still‑emerging name in a respected but not flagship chromium brand. It’s aggressive, but consistent with modern prospecting behavior around unique cards.

Grade vs. eye appeal

A PSA NM 7 might sound low if you’re used to gem-mint modern cards, but 1/1 SuperFractors live in a slightly different category:

• Collectors prioritize owning the only copy over squeezing maximum card grade.
• A PSA/DNA GEM MT 10 autograph is a strong plus, signaling a clean, bold signature.
• Slight corner or surface issues that push a card into the NM range often matter less when there is no higher-graded alternative—and no second copy at all.

In other words, the 7 grade may have tempered the final number a bit compared to a hypothetical PSA 9 or 10, but it doesn’t remove the card from “centerpiece” territory for a Kon Knueppel collector.

How this sale fits into the broader hobby

1. Ultra-modern risk and reward

Ultra-modern cards (roughly post‑2015) are heavily influenced by:

• Fast-moving prospect cycles
• Social media visibility
• A larger base of active buyers who track young players closely

In that environment, a unique rookie SuperFractor auto selling for five figures at Goldin signals that at least one buyer has strong conviction in the player’s potential or the card’s long-term desirability.

2. Auction house signal

Goldin is one of the most visible auction platforms in the hobby. When a card sells there on May 1, 2026 for $17,080, it provides a useful public marker for:

• How high-end collectors are currently valuing Kon Knueppel’s top-tier rookies
• How much weight is given to a Finest SuperFractor compared with other brands

Future consignors and buyers will likely refer back to this result when evaluating other key Knueppel cards.

3. What collectors can take away

If you’re a collector or small seller watching this space, a few practical notes:

• Serial numbering really matters. There’s a huge price gap between a /199 refractor auto and a true 1/1 SuperFractor, even with the same player and set.
• Autograph grade can be a tiebreaker. PSA/DNA GEM MT 10 helps cement this as a premium piece even with the card at NM 7.
• Brand and insert hierarchy count. Within Topps Finest, an Electrifying Signatures SuperFractor rookie auto is about as high as it gets.

None of this guarantees where prices go next, but it does show what the market was willing to pay at a specific moment.

Final thoughts

The 2025-26 Topps Finest Electrifying Signatures SuperFractor #ESG-KK Kon Knueppel Signed Rookie Card (#1/1), PSA NM 7 with a PSA/DNA GEM MT 10 auto, selling for $17,080 at Goldin on May 1, 2026, is a clear data point for:

• How collectors are currently valuing unique, ultra-modern rookie autos
• Where a non-flagship but respected chromium brand like Finest fits in the hierarchy
• The ongoing appetite for high-end prospect cards, even when the on-field résumé is still being written

For Kon Knueppel collectors, this is arguably one of the cornerstone cards in the entire player run. For the broader hobby, it’s another reminder that in the ultra-modern era, the combination of 1/1, rookie, on-card auto, and a strong brand can command serious attention—and serious money.
