How to Tell if a Penny Is Rare and Valuable

Some pennies hold significant worth for collectors, despite their humble face value. While most circulating pennies are worth one cent, specific characteristics make certain coins highly sought after. Understanding these features is the first step toward identifying a potentially valuable penny. This article details the key attributes contributing to a penny’s rarity and provides visual cues for notable examples.

Key Features Indicating Rarity

A penny’s value extends beyond its face value when it possesses key features indicating rarity. The date and mint mark are fundamental in determining a coin’s scarcity. Mint marks, small letters typically below the date, indicate production location: “S” for San Francisco, “D” for Denver, and no mark for Philadelphia. Pennies with low mintage numbers for a specific date and mint mark combination are more valuable.

Minting errors and varieties can increase a penny’s worth. A doubled die error occurs when the coin’s design, like the date or lettering, appears blurred or shadowed. This results from the die striking the coin blank multiple times slightly out of alignment. More pronounced doubling increases potential value. Other errors include off-center strikes, where the coin blank was not perfectly centered, leading to a missing or misaligned design portion.

Re-punched mint marks (RPMs) are another variety, typically seen on older coins, where the mint mark was punched more than once, creating an overlapping or misaligned appearance. Mint marks were hand-punched into dies until the 1990s, making RPMs common for earlier issues. Additionally, pennies struck on wrong metal planchets or those with clipped planchets, where a curved piece is missing from the coin’s edge, can also command higher values.

A penny’s physical condition and assigned grade significantly influence its market value. Coins with minimal wear, scratches, or corrosion are more valuable than heavily circulated or damaged ones. Professional coin grading services evaluate condition using the Sheldon Scale, assigning a numerical grade from 1 to 70. A grade of 70 represents a perfect, uncirculated coin. Higher grades indicate better preservation and correlate with higher prices.

Identifying Specific Valuable Pennies

Several specific pennies are renowned for their rarity and value, each possessing distinct identifying characteristics.

• The 1909-S VDB Lincoln Cent: Identify this highly sought-after coin by the “S” mint mark below the date and the designer’s initials “VDB” prominently displayed between the wheat stalks on the reverse. Only 484,000 were minted in San Francisco, making them exceptionally scarce. The “VDB” initials caused controversy upon release, leading to their swift removal.
• The 1914-D Lincoln Cent: This is a key date known for its low mintage at the Denver Mint. While it may not feature a striking error, its limited production numbers make it valuable, particularly in higher grades. Locating the “D” mint mark below the date is crucial for identifying this specific coin. Its value is primarily driven by its scarcity.
• The 1922 No D Penny: This unique variety has the “D” mint mark, indicating Denver production, entirely missing. This absence is due to a filled die, where the mint mark area was obstructed during striking. These pennies were indeed minted in Denver, but they appear to be from Philadelphia, making the missing “D” a significant error. Collectors must carefully examine the area below the date.
• The 1943 Copper Penny: An exceptionally rare error coin, mistakenly struck on bronze (copper) planchets during World War II. Pennies were supposed to be made of zinc-coated steel to conserve copper. A genuine 1943 copper penny will not stick to a magnet, unlike its common steel counterpart. It also weighs approximately 3.11 grams and has a distinct copper color.
• The 1944 Steel Penny: This rare error occurred when leftover steel planchets from 1943 were inadvertently used to strike pennies in 1944. These pennies will attract a magnet and have a silvery-gray appearance, contrasting with the reddish-brown of regular 1944 copper pennies. Identifying this coin involves both a visual check of its color and a magnet test.
• The 1955 Doubled Die Obverse Penny: Exhibits pronounced doubling on the date and the lettering of “LIBERTY” and “IN GOD WE TRUST” on the front (obverse) of the coin. This doubling is significant enough to be visible to the naked eye or with minimal magnification. This error occurred when the coin die shifted slightly during the hubbing process.
• The 1969-S Doubled Die Obverse Penny: Features doubling on the date and lettering, though it is often less dramatic than the 1955 variety. Early examples were initially suspected of being counterfeits by the government due to the unusual doubling. Examination with a magnifying glass is often necessary to clearly discern the doubling on this particular issue.
• The 1972 Doubled Die Obverse Penny: Characterized by a clear doubling on the date and the motto “IN GOD WE TRUST” and “LIBERTY.” This error, while not as rare as some earlier doubled dies, is still highly collectible and can be identified by carefully inspecting these areas of the coin. The clarity of the doubling contributes directly to its value.
• The 1983 Doubled Die Reverse Penny: Displays doubling on the lettering found on the back (reverse) of the coin. This error specifically affects the words “ONE CENT” and “UNITED STATES OF AMERICA.” Careful inspection of these elements with magnification can reveal the distinctive doubled appearance. This penny stands out as a modern error primarily affecting the reverse design.
• The 1992 Close AM Penny: Refers to a specific variety where the letters “A” and “M” in “AMERICA” on the reverse are nearly touching at their bases. This design, intended for 1993 and later issues, was mistakenly used on a small number of 1992 pennies from both Philadelphia and Denver mints. The common 1992 penny has a wider space between these letters, making the “Close AM” a rare transitional error.
• The 1995 Doubled Die Obverse Penny: Shows noticeable doubling on the words “LIBERTY” and “IN GOD WE TRUST,” as well as the date. This error is typically quite clear and can be identified by examining these areas on the coin’s front. This particular doubled die is one of the more recognized modern errors among collectors.

Verifying and Preserving Potential Finds

Once you identify a potentially rare penny, proper handling and preservation are paramount. Avoid cleaning the coin, as this causes irreversible damage and diminishes its value. Always handle coins by their edges to prevent transferring skin oils, which can lead to corrosion. Store the coin in a non-PVC holder, such as Mylar or archival-safe plastic flips, to protect it from environmental damage.

For initial verification, consult reputable online resources and current coin price guides. Websites of established coin dealers or numismatic associations often provide images and descriptions of known rare varieties. These resources allow for a comparison with your find and offer an estimated value range based on the coin’s type and condition.

If preliminary research suggests the penny is rare and valuable, consider a professional appraisal or grading service. Organizations like the Professional Coin Grading Service (PCGS) and the Numismatic Guaranty Corporation (NGC) are third-party grading services. They authenticate coins and assign a numerical grade based on the Sheldon Scale. These services provide an assessment of a coin’s condition and authenticity, crucial for maximizing its market value.

The cost for professional grading varies depending on the coin’s value, turnaround time, and the grading service chosen. Fees can range from approximately $22 to over $150 per coin, not including potential membership fees or shipping. This investment is justified for coins with potential value, as it provides credibility and enhances their liquidity in the collector’s market.
