Upper Deck has their own version of the Topps refractor and they call it a rainbow foil and I have been using holo foil to cut down on characters for eBay listings.

This sports card review features 1999-2000 Upper Deck Encore Michael Jordan within the Jamboree insert set and card number J1.

I will first list my scores and next provide Grok’s AI scores. During my initial review, I cross referenced 5-10 graded cards.

Overall self-grade for this card is 9.5 Mint+.

Grok AI Scores

As a simulated BGS/SGC/PSA grader, here’s a professional hypothetical grading assessment for the 1999-2000 Upper Deck Encore Jamboree Holo Foil Michael Jordan card (#J1, the holo foil parallel from the Jamboree insert set—confirmed as a scarce foil/holographic parallel with radiant rainbow holo effect, red/purple foil accents, embossed “Encore” and “Air Force” text, circular crowd photo, and premium glossy stock). This is based on the provided photos (front dunking pose with green net/holo shine, red/black/purple foil borders, “Encore” text, back bio on Slam Dunk history with red curved text and hologram stamp, close-ups of edges/corners/foil/surface).Upper Deck Encore from 1999-2000 features high-end inserts with holographic foil, radiant refractors, and textured/glossy finishes—prone to grading challenges like foil chipping/lifting (especially on accents/stamps), surface scratches/dimples in holo areas (rainbow patterns highlight specks/lines under light), edge whitening/roughness from thick stock, corner softness/fuzz, and centering variances (factory cuts often slightly off on inserts). The Jamboree holo foil parallel amplifies reflectivity, making any surface/foil imperfection more visible.The photos show excellent eye appeal: vibrant colors, sharp focus on Jordan’s iconic dunk, strong holo rainbow shine (no major dulling), intact foil accents (no heavy chipping visible), clean back text/bio/hologram, no creases/bends/stains/wax. Close-ups reveal potential issues: subtle edge roughness or micro-whitening (especially lower corners and white borders), minor corner softness (slight fuzz or ding on bottom corners), possible light surface dimples/lines in the holo background (common on foil refractors under magnification/angled light), and foil registration variance or micro-imperfections on the red/purple accents. No blatant defects like dents, major scratches, or centering problems, but late-90s Upper Deck foils/holograms often get dinged for these in pro grading.

Populations for this Jamboree #J1 holo foil are low (scarce parallel; PSA/BGS data shows limited high-grade submissions for Encore inserts, with many capping at 9 due to foil/surface/edge issues—e.g., PSA 10s exist but rare, BGS Pristine even rarer). Raw copies sell modestly ($20-100+ depending on shine/condition), graded highs add value (PSA 10s historically $150-300+, BGS 9.5 similar or higher).BGS (Beckett Grading Services) Hypothetical Grade & SubgradesBGS is strict on late-90s foil/holo inserts—subgrades expose holo surface flaws, foil condition, and edge wear.Centering: Front balanced (likely 55/45 or better; borders even, holo aligned). Back solid. Subgrade: 9.5

Corners: Mostly sharp; close-ups show minor softness/micro-fuzz/whitening (typical for foil stock handling). Subgrade: 9

Edges: Smooth overall; potential micro-roughness/whitening on white borders and foil edges (common on Encore holo). Subgrade: 9

Surface: Glossy with radiant holo shine; clean to naked eye, but likely light dimples/lines/scratches in foil background under loupe (reflectivity highlights these). Subgrade: 9

Overall BGS Grade: 9 Gem Mint

(Strong late-90s foil example; surface/foil/edges likely cap it from 9.5. Pristine 10 rare due to holo vulnerabilities.)

PSA (Professional Sports Authenticator) Hypothetical GradePSA grades holistically (vintage insert tolerance ~60/40 centering for 10, near-perfect corners/edges/surface, no major defects).Excellent eye appeal: sharp pose, full gloss/holo pop, no impairing issues.

Centering within tolerances.

Minor edge whitening, corner softness, or holo surface variance (dimples/lines) could prevent straight 10—PSA dings foil/holo for physical flaws.

Overall PSA Grade: 9 Mint

(Could push to Gem Mint 10 if lenient on micro-issues—many clean Encore Jamboree foils hit 9-10, but surface/foil often results in 9s. No qualifiers like OC expected.)
