Is a 'real' one dollar bill half the usual size worth anything?

Answer 1

Since 1928, all US currency bills are the same size (the size they are now). Some were once a little larger, 3 1/8" by 7 3/8", or 7.9 cm by 18.7 cm -- they are called "horse blanket" notes. Anything other than those two sizes is a "reproduction" (copy, fake) made smaller because copies are not allowed to be the same size as real currency. There are some miniature one-dollar bills that were printed in 1988 for a market promotion. Those bills and any like them are essentially worthless except as collectible novelties.

Answer 2

A 'real' one dollar bill that has been half the usual size is considered damaged or mutilated by the U.S. Department of Treasury. It is no longer considered legal tender and cannot be used for transactions. However, it may still have some value to collectors as a novelty item.
