[Utah Currency] Recognizing the need for a temporary circulating medium superior to packets of gold dust, Brigham Young and his associates made plans to issue paper currency until coins could once more be minted. The first issue consisted of small bills, two inches wide and four inches long, hand-printed by pen and ink on plain white paper (there was not yet a printing press in the region). Bills were made for 50 cents, $1.00, $2.00, $3.00, and $5.00, and were signed by Brigham Young, Heber C. Kimball (Brigham Young's counselor), and Newel K. Whitney, presiding bishop of the church. The bills were stamped with the seal of the Twelve Apostles, which consisted of the emblem of the priesthood encircled by sixteen letters: P.S.T.A. P.C.J.C.L.D.S. L.D.A.O.W., which was an abbreviation for "Private Seal of the Twelve Apostles, Priests of the Church of Jesus Christ of Latter-day Saints, in the Last Dispensation All Over the World." All of the 830 notes in the initial issue, with a face value of $1,365.00, bore the date January 2, 1849."
