When we talk about coins with mint marks, or those which we expect to have mint marks that don’t, we are usually talking about coins produced in the United States. Several mints have produced coins for US legal tender over the years including Philadelphia, San Francisco and New Orleans.
If you have a US coin and you expect to find a mint mark close to the year of production but can’t find one, this usually means it was struck in Philadelphia. It could mean the coin is so old that it was produced before mint marks were regularly used – before 1838. Alternatively, the coin could have been produced between 1965 and 1967 when there was a halt in the striking of mint marks.
Today, we have assembled all the relevant and interesting information in an effort to answer the question “what does no mint mark on a coin mean?”. We have also included a mint mark chart for easy reference.
Brief History Of Mints And Mint Marks In The US
The United States has had several mints throughout its history, each with its own unique history and mint marks. The first US mint was established in 1792 in Philadelphia, Pennsylvania. As the only mint in production for over 60 years, it did not use a mint mark as it was not necessary to differentiate between mints yet.
In 1835, a Congressional Act decreed the use of mint marks and established several Mint branches in 1838. These locations included New Orleans which began using an “O” mint mark on its coins, and the Charlotte, Dahlonega mints. Later, in 1854, the San Francisco mint was established. Each of these mints used a different mint mark to indicate the location where the coin was minted.
During this time, the Philadelphia mint used no mint mark to distinguish its coins from those of other mints.
What Does It Mean When There Is No Mint Mark On A Coin?
When a coin does not have a mint mark, it means that the coin was likely produced at the United States Mint in Philadelphia. Mint marks are small letters or symbols on a coin that indicate the mint where the coin was produced. For most of US coinage history, coins produced at the Philadelphia mint did not bear a mint mark, whereas coins produced at other mints, such as San Francisco or Denver, did bear mint marks.
The lack of a mint mark on a coin can also indicate the time period in which it was produced. The Philadelphia mint did not use a mint mark on its coins until 1838, and some coins produced at other mints were struck without a mint mark due to production concerns or other factors. Additionally, some coins produced at the Philadelphia mint between 1965 and 1979 were struck without a mint mark due to a temporary hiatus in their usage.
Between 1965 and 1967, coins from other mints were also struck without a mint mark. This was due to thrifty coin collectors hoarding coins to sell on in uncirculated condition in the future – an investment of sorts. Unfortunately this caused a coin shortage, and disguising the mint location deterred collectors from coin hoarding.
Is it possible your coin is from a different country? There are many countries around the world which do not use mint marks on their coinage. Just a few examples include New Zealand, Japan and China, but there are many more!
While the absence of a mint mark does not necessarily make a coin rare or valuable, it can affect its historical significance and rarity. Collectors and researchers use mint marks to understand the production history of a coin, and coins without a mint mark can provide insight into the early years of US coinage. Additionally, some coins without a mint mark may be more valuable due to their rarity or historical significance.
The Philadelphia Mint
The Philadelphia Mint is the oldest operating mint in the United States and has been in continuous operation since it was founded in 1792. The mint was established by an Act of Congress in response to the need for a national mint to produce and regulate US coinage. At the time, the US government was struggling to produce consistent and reliable coins, and counterfeiting was rampant.
The mint was originally located in Philadelphia’s downtown area, but it moved to a larger facility on Spring Garden Street in 1833. The new building was designed by William Strickland, a prominent Philadelphia architect, and it was considered a technological marvel at the time. The building featured advanced security features and state-of-the-art equipment, and it could produce up to 50 million coins per year.
Throughout its history, the Philadelphia Mint has produced a wide variety of coins, including the first US silver dollar, the first US gold coins, and the famous Morgan Silver Dollar. The mint has also played a vital role in the production of commemorative coins, medals, and other numismatic items.
Despite its long history, the Philadelphia Mint has undergone many changes over the years. In the early 1900s, the mint began to shift its focus from traditional coinage to the production of commemorative coins and other numismatic items. In the 1960s, the mint stopped producing silver coins for circulation and began to focus on producing proof and uncirculated coin sets for collectors.
Today, the Philadelphia Mint remains an important part of the US Mint system and continues to produce coins and other numismatic items for collectors and investors. While the mint no longer produces coins for circulation, it remains an important part of US numismatic history and is a popular destination for visitors interested in learning more about the history of US coinage.

Do All Countries Use Mint Marks?
No, not all countries around the world produce coins with mint marks. Mint marks are typically used by countries that have multiple mints that produce coins, and they serve as a method to identify the exact mint that produced a given coin.
While the United States is perhaps the most well-known example of a country that uses mint marks on its coins, many other countries also use them. Some examples include Canada, Australia, and the United Kingdom. In these countries, mint marks are typically letters or symbols that indicate the specific mint where a coin was produced.
However, not all countries use mint marks on their coins. In some cases, this is because the country only has one mint that produces coins. For example, the New Zealand Mint is the only mint that produces coins for New Zealand, so it does not use mint marks on its coins.
In other cases, countries may not use mint marks for cultural or historical reasons. For example, some countries with a long history of producing coins, such as Japan and China, do not use mint marks on their coins. In these cases, the coins may instead feature other design elements that indicate the year or era in which they were produced. For example, Japanese coins typically feature the era name, which changes when a new emperor ascends to the throne. Similarly, Israeli coins often feature images or symbols that represent significant events or figures from the country’s history.
Examples of countries that use mint marks on their coins:
- United States
- United Kingdom
- South Africa
Examples of countries that do not use mint marks on their coins:
- New Zealand
Are coins without a mint mark rare?
Coins without a mint mark are not necessarily rare, as many coins produced at the Philadelphia mint were struck without a mint mark. However, some coins without a mint mark may be more valuable than others due to their rarity, historical significance, or other factors.
What is the purpose of a mint mark?
The purpose of a mint mark is to identify the location where the coin was minted. Mint marks can help collectors and researchers understand the production history of a coin and its rarity. Additionally, mint marks can sometimes affect the value of a coin, as coins produced at certain mints may be more valuable due to lower mintage (making them rarer), or error coins.
Can a coin have more than one mint mark?
A regular US coin can only have one mint mark, which indicates where the coin was produced. However, some coins may have multiple varieties or different designs that were produced at different mints, which can affect their value and rarity. Alternatively, some error coins may bear more than on mint mark due to, for example, planchet or double die errors from different mints.
