What gifts are good for a comic collector who seems to have everything?

For the collector who seemingly has it all, focus on scarcity or quality. Consider rare variant covers, professionally graded comics (if you know their preferences), original comic art, signed copies of their favorite issues, or high-end, limited-edition statues or busts. High-quality archival storage solutions like acid-free bags and boards, specialized display cases for graded comics, or custom shelving units can also be invaluable.
