These large-sized notes are a "must have" for every collector, because they're America's very first $1 Silver Certificates. And not only are these colorful notes scarce, but series 1886 and 1891 are also the only U.S. notes to feature Martha Washington on the face. As you know, she was the wife of George Washington, but did you also know she's the only non-allegorical female shown on U.S. paper money - an added bonus! Every collector needs at least one of these notes, but our supply is limited. So be sure to secure yours today.
