A full sticker album is paper, glue, and nostalgia in one volume. A loose glossy sticker curls as soon as it lies next to the heater. In the overview Security for collectors, this belongs with paper that has a collector price, truly high only for a few images.
What breaks without a thief
Gluing them in later warps the page and shines differently from the original. Light eats the red tones. Moisture loosens the gum. You store albums upright, not in full sun, not in a box on the damp floor. Full albums and open packs stay two stocks, because the price often hangs on the unopened pack.
When someone comes
For most albums the offender stays indifferent. For the few expensive sets, sealed or complete, the same applies as for other cards: small, known, light. They do not sit on the children's shelf at eye level toward the door. They sit with the other small valuables in the cabinet, if the sum allows it.
The folder
Year, publisher, complete or with gaps, sealed or glued. For an expensive set, the receipt. You describe the rest as a box of year groups, so that water damage has a number and not a tale.
