Yes, Journey series bills are dated "Issue of 2001" (or newer) at the bottom right corner of the face (not back) of the bill. The "Issue of" date is what is used to determine the series of the bill. The "Printed in" date debuted on the Journey series bills, and gives collectors a whole new area to specialize in; especially when the "printed in" date changes in the middle of a prefix causing a short run variety.
