12 Misprint Stamps Whose Flaws Made Them Famous

Misprint stamps are the kind of collecting story that makes people stop and look twice, even if they have never owned an album. A tiny mistake in color, alignment, perforations, or overprints can turn an ordinary issue into something collectors talk about for decades. What makes these stamps so interesting is that the flaw is not just a defect, it is a snapshot of how printing really works when something goes wrong. Some errors are obvious right away, while others stay hidden until someone spots the difference under the right light or next to a normal copy. Values can climb fast when an error is rare, well documented, and backed by expert verification.
