The market for Christmas collectibles is actually on the rise, according to Terry Kovel, co-author of the Kovels' Antiques & Collectibles Price Guide. "All of the holidays have gotten more popular in collecting," she tells GoodHousekeeping.com. "And the most popular one obviously is Christmas." Vintage cards in good condition can fetch about $10 to $50 apiece, she says, but particularly valuable ones can shoot up into the three- or even four-figure range.
Pop-up cards are normally cards that, once opened, have a picture coming outward, giving the reader a surprise. Pictures and printed messages in greeting cards come in various styles, from fine art to humorous to profane. Non-specific cards, unrelated to any occasion, might feature a picture (or a pocket to paste in a personal photograph) but no pre-printed message. Paper Pop Cards has a patent for detachable pop-up cards which lets the pop-up be saved as Keepsake.
