Every sports product line has its own grading “personality.”
Knowing them helps you avoid bad grading candidates.
Panini Prizm
most scratch-prone chrome surface in the hobby
print lines everywhere
edges chip easily
centering often left-right skewed
Topps Chrome
cleaner print quality, but:
roller lines
foil dimples
occasional indent circles
Select / Optic
bends/warps more than most sets
concave bowing is common
color surfaces show fingerprint oils heavily
National Treasures / Flawless / Immaculate
thicker cards = corner pressure
edge chipping on patch windows
foil borders scratch extremely easily
Bowman Chrome / Sapphire
excellent surface quality
much better centering
but print dots (“snow”) are common on some runs
Each set has patterns.
