Common. Military Payment Certificates from the 1968 period were produced in substantial quantities for active circulation in military establishments worldwide. Series 661 represents a standard production run without known scarcity factors. The denomination (10 cents) and series are typical examples of routine MPC issuance, and uncirculated examples remain readily available in the collector market.
Military Payment Certificates were issued by the U.S. Army to prevent currency speculation and unauthorized black market activities in overseas military establishments during the Cold War and Vietnam War periods. The 1968 date places this note during the height of American military presence in Southeast Asia, when MPCs were actively circulated at U.S. bases worldwide. The restrictive inscription limiting use to 'United States military establishments by United States authorized personnel' reflects the tight security controls imposed during this geopolitically sensitive period.
The obverse features a classical right-facing profile portrait of a person wearing a headwrap or head covering, rendered in fine engraving style within an ornate decorative border with circular ornamental designs at the corners. A landscape is visible in the background behind the portrait. The reverse displays the military payment certificate's formal authorization text within a decorative cartouche, surrounded by four symmetrical sunflower or rosette pattern designs in the corners and an ornate border frame. The entire design employs intricate geometric line patterns and fine engraving work, characteristic of high-security currency production, with a consistent color palette of blue, purple/maroon, and white/cream throughout both sides.
