Are graded unopened packs worth more?
Often, but not always. The premium depends on format, grade, scarcity, buyer confidence and recent sold comps.
Can I know exactly what is inside?
Usually no. You can use format, era, wrapper type and visible clues to narrow expectations, but sealed collecting is built around uncertainty.
How do I spot a reseal?
Compare crimp symmetry, wrapper tension, seam texture, heat shine, cello clarity and seller photos. Use the scorecard when several concerns appear together.
Should I open a sealed pack?
That is a collector choice, but opening destroys the sealed premium. Research sold sealed value and opened-card expectations first.
What matters most for storage?
Stable temperature, low humidity, no compression, no sunlight and a storage method that avoids bending corners or stressing seams.
