First up, the touch. Real U.S. currency isn’t just any old paper; it’s a special blend of 75% cotton and 25% linen. That means it has a distinct, slightly rough texture that feels almost like fabric.
A fake twenty, on the other hand, often feels smooth or even waxy, like printer paper. Run your thumb along Jackson’s shoulder — if it feels flat and slick, you might have a dud. If it feels like you’re rubbing a sturdy napkin, you’re probably good.
Pro tip: Compare it side-by-side with a bill you know is real. Your fingers are smart; listen to them.
