Tracking the exact number of coins produced by the U.S. Mint can be surprisingly tricky, especially when diving into the history of minting practices.
For coin collectors and history buffs, understanding the numbers isn’t just about knowing production totals—it’s about unraveling a story of changing practices, fiscal years, and record-keeping quirks.
Where Do Coin Records Come From?
Most modern coin production numbers come from the U.S. Mint’s press releases and annual reports. Since 1873, after a major reorganization of Mint operations, the Director of the Mint’s reports became the go-to source for tracking coin production, even into the 1960s.
These records also shed light on the production of prized “Proof Coins,” which were often minted in extremely limited quantities—sometimes only a dozen or a few thousand per year.
But what about records before 1873? Things get a bit more complicated. Before this time, the U.S. Mint reported coin production based on the government’s fiscal year (July 1 to June 30 of the next year).
This means coins dated for a specific calendar year may not match the actual production timeline, creating confusion for collectors.
The Challenge of Matching Coin Dates
To add to the complexity, coins minted in December were often dated for the following year, as they were distributed in January.
Similarly, mints sometimes used old dies for several months into the new year, stamping coins with dates from the previous year. These practices make it difficult to pinpoint exactly how many coins were produced with specific dates.

A Hidden Resource: The Paying Teller’s Blotter (PTB)
One lesser-known source of coin data is the Paying Teller’s Blotter (PTB). This journal acted as a daily record of transactions at the Mint, documenting when coins were delivered by the Chief Coiner.
By using the PTB, researchers can piece together a more detailed picture of when coins were produced, separating fiscal year data into distinct calendar years.
For example, the fiscal year 1861 began on July 1, 1860, and ended on June 30, 1861. Coins produced during this period were dated either 1860 or 1861, depending on when they were made. The PTB helps clarify these distinctions, offering a clearer breakdown of production numbers.
Comparing PTB Data to Official Mint Reports
When comparing PTB records to official Mint reports for fiscal year 1861, significant differences emerge. These discrepancies suggest that errors—or perhaps unknown factors—might have affected the official numbers. For example:
- Some coins listed in fiscal year tables were produced in different calendar years.
- Proof coins, which were handled separately, weren’t included in circulating coin totals, further complicating the records.
How Does the PTB Compare to the Red Book?
The Guide Book of United States Coins (commonly called the Red Book) is a standard reference for collectors, but even it doesn’t always match PTB records. For example:
- In 1860, the PTB showed slightly higher totals for dimes and cents compared to the Red Book.
- The Red Book lists 1,666 more double eagles than the PTB for the same year—a difference of $33,320.
While some differences might stem from assumptions about coin dates around New Year’s, the PTB data for late 1859 and early 1861 show no unusual entries.

Why Do These Discrepancies Matter?
For collectors and researchers, understanding these discrepancies isn’t just about numbers—it’s about gaining insight into historical minting practices.
The PTB provides a rare, detailed look at how coins were delivered and recorded, offering a valuable tool for anyone trying to make sense of the Mint’s complex history.
