The most common book of stamps you’ll find in the U.S. has 20 stamps inside. Yes, twenty little squares of sticky paper, all ready to carry your mail across town or across the country. But here’s the kicker: that number isn’t written in stone.
You can also grab a “coil” of 100 stamps, a tiny booklet of 10, or even a single stamp if you’re feeling minimalist. So really, a “book” is just a suggestion—like getting a dozen donuts when you only wanted six. Why does this matter? Because it changes how you think about your stamp stash.
