Variant Breakdown & Pricing Averages
By separating sales over the last 30 days into isolated print runs, collectors can pinpoint accurate market values and locate potential buying inefficiencies:
1. The Base Card Tier (Raw Only)
The standard, unnumbered portrait insert serves as the volume baseline, displaying steady demand from casual collectors and set-builders.
- Variant Average Price: $4.55
- Price Range: $2.50 – $7.99
- Market Trend: Standard raw auction listings show a tight cluster between $2.50 and $6.50. Fixed-price buy-it-now items establish a slight premium, settling between $7.00 and $7.99.
- Collector Strategy: At this price point, keep a sharp eye on delivery costs. While early auctions closed at $2.50 with a minimal $0.50 shipping charge, another closed at $4.25 but required a $3.05 shipping fee. Total net acquisition cost should always dictate your bidding limits.
2. Night Vision Mini-Diamond Parallel (/299)
The unnumbered short-printed Night Vision theme acts as a highly popular and affordable parallel target, showing clean, predictable value over the last 30 days.
- Variant Average Price: $8.35
- Price Range: $4.25 – $14.00
- Market Trend: Raw open auctions successfully realized closing baselines of $4.25, $6.50, $7.50, and $7.52. Meanwhile, fixed-price immediate stock pulled a strong premium, changing hands at $11.00 and $14.00.
3. Mid-Tier Serial-Numbered Parallels (/199 down to /99)
As true serial-numbered color variants hit the board, collector competition ramps up, causing a stark jump in average prices:
- Blue Mini-Diamond Parallel (/150) Variant Average: $9.45. Interestingly, the Blue tier is displaying a temporary market inefficiency. Two separate copies closed via raw auctions at lower boundaries of $8.00 and $10.89, placing it lower than the fixed-price Night Vision sales. This represents an excellent buy-low opportunity for alert collectors.
- Purple Parallel (/199) Variant Average: $18.33. Demand for Piastri’s Purple tier remains incredibly rigid. Over the last 30 days, three separate copies found homes at $15.50 (auction), $18.00 (fixed price), and $21.50 (auction), solidifying a very reliable valuation pocket.
- Green Refractor Parallel (/99): Breaking under the 100-copy threshold, a single raw Green parallel captured a strong $30.00 fixed price.
4. Premium Low-Numbered Parallels (/50)
The absolute ceiling for the raw market over the last 30 days concentrates around low-print, highly-coveted precious metal subsets:
- Gold Mini-Diamond Refractor (/50): Highlighting the robust collector intent for low-print McLaren targets, a raw copy of the Gold Mini-Diamond parallel ignited an 11-bid war before hammering down at a peak price of $76.00.
PSA Graded Sales & Market Strategy
According to product research data over the last 30 days, officially graded copies (such as PSA 9 or PSA 10 slabs) have not yet recorded transactions for this specific card number, indicating that the current market landscape is completely raw-driven.
Strategic Insights for Submitting to PSA:
- Evaluating the Baseline: With raw base cards trading around a modest $4.55 average, submission fees make grading basic inserts tough to justify unless intended solely for a personal player registry.
- The Arbitrage Target: Collectors should look to target the **Blue Mini-Diamond /150** (given its current sub-$10 auction entries) or the **Gold Mini-Diamond /50**. Acquiring clean raw parallel copies at these baselines and securing a Gem Mint PSA 10 slab will maximize your return on investment, as registry collectors will actively pay a heavy condition premium to insulate low-numbered color assets from the circulating raw supply.
