Military Payment Certificate

Conversion Page

I buy MPC so convert yours now to U.S. Dollars!

I have been collecting MPC and other military currencies for quite some time. I find it very entertaining and informative. I also enjoy studying military history. And with MPC, I found an area that combines my two hobby interests - history, and note collecting. I have an extensive MPC and military currency collection and love researching information on MPC and other military currencies.

One of the main reasons Military Payment Certificates were originally invented was to prevent having to use large amounts of US dollars overseas. This would prevent legal tender US dollars from ever being captured by the enemy and used against the USA. The first use of what is considered MPC was during the invasion of Okinawa when troops were issued what are called Series "A" yen notes. Soldiers turned in their "greenbacks" and were issued Series "A" notes in exchange. See a wonderful picture of this here. 

Following WWII, and with the success of the "A" yen notes, regular MPC notes were issued. Another reason for issuing MPC was that it helped combat black market activities. Any amount of MPC could be converted to the local currency by occupying US troops, but once converted, it could not be reconverted, effectively insulating the US dollar. A soldier being paid in MPC, could convert some or all of his pay to yen or marks for example, but could only send MPC home. A soldier dealing in the black market would be hampered trying to get his ill gotten gains back home. MPC was issued to service personnel and some types of civilians, and it was used much like regular money, except MPC could not be used as a form of payment to entities outside the influence of the U.S. government without special permission. MPC could be used on bases, ships, canteens, and other similar places but could not be used to buy local goods or services without special permission and only by those merchants authorized to accept MPC.

Although security measures were in place, MPC would eventually find its way into the local economy by fraud, theft, or other means. When officials felt that substantial quantities of MPC were embedded into the local economy, or that the current series of MPC was in some other way being compromised, another series would be released to replace and devalue the current one. Only those personnel authorized to have MPC when C-Day, or Conversion Day, rolled around, had the chance to convert their soon to be worthless MPC to the newly issued MPC and retain their value. No notice would be given when a C-Day would come. Bases would be closed, no passes were issued, - in essence a lockdown, and on that single day you had to convert your current MPC or risk "losing your money". Once converted and turned in, the old MPC was destroyed - usually by burning. The black marketers, pushers, and other non-authorized individuals were now stuck with worthless paper thus effectively disarming them from their underground activities. To see a great picture of a C-Day, click here. This C-day was on March 10, 1947 and the soldiers pictured were turning in their Series 461 notes, and receiving Series 471 notes.

There were 13 issues of MPC officially released beginning with 461 and ending with 692. Many of these issued notes have survived C-Day. Some were placed into books or other documents and stored until found later. Some were sent home to families from personnel overseas as a memento, keepsake, or just curiosities - these notes usually have a location or a date written on them. Still others found their way coming home with service personnel and dependents. Even the notes the black marketers were stuck with, after all these years, are still being rescued and brought home from their exile.

Rich with history. Beautiful for their designs. Remarkable for their importance. And treasured for their romanticism. MPC notes were used around the world. They have some of the most innovative and provocative designs ever seen on paper currency. Issued to help our country maintain its importance in the world, they served a most noble purpose. Just like the soldiers they served, some show their scars more than others, and not all made it home. If only they could talk - the tales they could tell.


Do you have MPC you wish to sell? If the answer is yes, then follow these easy steps:

1) Determine the series and denomination. -- All MPC notes have a series number. This is comparable to the "date" on regular US money. The series number will always be found on the front of the note, but not always in the same place. The series number consists of 3 digits, the first two being the year, and the last digit being the issue printing. So for example, if you have a series 641 note. This signifies that the note was printed in 1964 and was the 1st issue printed. Series 692 signifies it was printed in 1969, and was the 2nd issue printed - Series 691 had already been printed. To determine the denomination is easy. MPC was printed in denominations of 5 10 25 50 $1 $5 $10 $20. Some early series do not contain the $20 denomination.

2) Get the serial number. -- All MPC notes have a serial number consisting of a letter, then 8 digits, then usually another letter. The serial number is also always found on the front of the note.

3) Email me a list of what you have. -- Click C-Day and email me a list of what you have to sell. I will write you back as quickly as possible. Use the format (Series) (Denomination) (Serial #). Please let me know any defect or detail that may need mentioning. For example:

Hi Brad,

    I have the following:  Series 481, .25 cents, D00058939D
    How much is this worth?

Once you have emailed me, I will try to make a ballpark offer on the notes. In some cases I will need to actually see the note (or at least a scan via email) to make a more detailed offer on high value notes. I will send you a check once I have examined and confirmed with you the amount I will pay. If you don't like my offer, I will send your notes back to you at my expense.


Here are some comments we've gotten in recently:

Terry in Overland Park KS - Brad made a good offer and
