What affects the value of Military Payment Certificate Series 661?

• Look for the characteristic blue and purple color palette unique to this specific series and denomination.
• Check for the female portrait on the left side of the note's face, a hallmark of the $1 Series 661 design.

History of Military Payment Certificate Series 661

Military Payment Certificates (MPC) were issued for use by U.S. military personnel serving overseas in various conflicts to prevent local black market activity and stabilize local economies. Series 661 was introduced in 1968 and primarily saw use during the Vietnam War. These notes were abruptly withdrawn and replaced during 'C-Day' events to render current black market holdings worthless.
