Lenticular 3D

Lenticular technology uses a specialized lens array to create the illusion of depth or motion (3D effect) when the card is tilted. Popularized by Sportflics in the 1980s and later used in brands like Kellogg's and Upper Deck, lenticular cards are exceptionally difficult to grade because the plastic surface is prone to cracking and the 'ghosting' of images can interfere with centering analysis.

Condition & Grading Challenges

Surface Issues: For this technology, look for 'Refractor Lines' (horizontal print lines) and 'Dimpling'. Chromium surfaces are extremely sensitive to fingerprints, which can degrade surface scores over time.

Investment Profile

Speculative Tech: Value drives from the scarcity of the parallel and the visual appeal of the technology (e.g., Atomic vs Wave patterns).
