In the world of numismatics, the 1970s might not immediately spring to mind as a decade of rare and valuable coins.
After all, it’s recent enough that many of us might have childhood memories of the period, and old enough that coins from that era are still in circulation.
However, hidden within the pocket change and forgotten piggy banks of America lie some surprising treasures from the disco decade.
Let’s dive into the world of 1970s coinage and uncover five high-value coins that might just be lurking in your spare change.
The Numismatic Landscape of the 1970s
Before we delve into our list, it’s worth setting the stage for coin collecting in the 1970s. This decade saw significant changes in U.S. coinage, including:
- The transition from silver to copper-nickel clad coins
- Fluctuations in mint production numbers
- The introduction of new commemorative designs
These factors combined to create a fertile ground for rarities and errors that excite collectors today. Now, let’s explore our top five high-value coins from this era.
1. The 1970-S Proof Washington Quarter on a Canadian Planchet
Estimated Value: $35,000 – $80,000
Our journey begins with a coin that shouldn’t exist – a 1970-S Proof Washington Quarter struck on a Canadian planchet. This numismatic anomaly occurred when a blank intended for a Canadian quarter somehow found its way into the San Francisco Mint’s proof production line.
The result? A quarter that’s slightly smaller and lighter than its American counterparts, with a composition of pure nickel instead of the standard copper-nickel clad. Only a handful of these coins are known to exist, making them incredibly rare and valuable.
What makes this error particularly fascinating is the international nature of the mistake. It’s not just a simple mix-up of planchets within the U.S. Mint system, but a cross-border blunder that resulted in a truly unique coin.
Collectors prize this coin not only for its rarity but also for the story it tells about mint operations and the potential for human error even in highly controlled environments. If you happen to have a 1970-S proof set tucked away, it might be worth taking a closer look at that quarter!
2. The 1972 Double Die Obverse Lincoln Cent
Estimated Value: $100 – $500 (depending on condition)
Next on our list is a coin that’s a bit more accessible but no less intriguing – the 1972 Double Die Obverse Lincoln Cent.
This error occurred during the hubbing process when the die was struck twice at slightly different angles, resulting in a noticeable doubling of the lettering and date on the obverse (front) side of the coin.
While not as rare as our Canadian planchet quarter, these double die pennies are still highly sought after by collectors. The doubling is most visible in the words “LIBERTY” and “IN GOD WE TRUST,” as well as in the date.
What makes this coin particularly interesting is that it’s an error that occurred before the minting process began, affecting an entire run of coins rather than just a single specimen.
Estimates suggest that about 20,000 of these coins entered circulation before the error was caught, making them rare enough to be valuable but common enough that finding one in your change jar isn’t out of the question.
The value of these coins can vary significantly based on condition. A well-worn example might fetch around $100, while a pristine, uncirculated specimen could command $500 or more. It’s a reminder that even the humble penny can hold surprising value!
3. The 1776-1976 Bicentennial Quarter with No S Mint Mark
Estimated Value: $80 – $200 (for circulated examples)
As the United States geared up to celebrate its bicentennial in 1976, the U.S. Mint produced a special series of coins featuring unique reverse designs for the quarter, half dollar, and dollar. These coins were minted in 1975 and 1976, all bearing the dual date “1776-1976.”
Among these commemorative coins, a particularly valuable variety emerged: the 1776-1976 quarter without the “S” mint mark.
Typically, all proof coins from this period were struck at the San Francisco Mint and bore the “S” mint mark. However, a small number of these bicentennial quarters were struck without the mint mark.
While proofs of this error can command tens of thousands of dollars, even circulated examples without the “S” are valued at $80 to $200 or more, depending on condition.
This error is particularly intriguing because it occurred on a high-profile commemorative coin, adding an extra layer of historical significance to an already noteworthy piece.
Collectors are drawn to this coin not just for its rarity, but for its connection to a pivotal moment in American history. It serves as a tangible link to the nation’s bicentennial celebrations and a reminder of the pride and patriotism that swept the country during that time.
4. The 1970-S Small Date Lincoln Cent
Estimated Value: $50 – $100 (for uncirculated examples)
Sometimes, value in numismatics comes not from errors, but from subtle variations in design. Such is the case with the 1970-S Small Date Lincoln Cent. This variety features a noticeably smaller date than the more common large date variety from the same year.
While not as dramatically valuable as some of the errors on our list, uncirculated examples of the small date variety can still fetch $50 to $100 or more. What makes this coin interesting is the story it tells about the minting process and the decisions made in coin design.
The existence of both small and large date varieties in the same year provides insight into the mint’s experimentation with different date sizes and the transition between styles.
It’s a reminder that even seemingly minor details in coin design can have significant implications for collectors decades later.
For the casual coin enthusiast, this variety offers an accessible entry point into the world of numismatic varieties. It’s a coin that rewards careful observation and attention to detail, traits that are at the heart of coin collecting as a hobby.
5. The 1974 Aluminum Penny
Estimated Value: Priceless (Illegal to Own)
We conclude our list with a coin that’s less a collecting opportunity and more a fascinating piece of numismatic history – the 1974 Aluminum Penny. In the early 1970s, rising copper prices led the U.S.
Mint to experiment with alternative materials for the one-cent coin. One of these experiments resulted in the production of about 1.5 million aluminum pennies dated 1974.
However, these coins were never officially released into circulation. The aluminum composition proved problematic for vending machines and was potentially harmful if ingested by children. As a result, nearly all of these coins were destroyed.
A few specimens are known to exist, primarily held by the Smithsonian Institution or former mint employees. Importantly, it is illegal for private individuals to own these coins, as they are considered government property that was never officially released.
While you won’t find one of these in your change jar (and if you did, you’d be legally obligated to return it), the 1974 Aluminum Penny represents a fascinating “what if” moment in American coinage.
It’s a reminder of the ongoing challenges faced by the mint in balancing economic considerations with practical concerns in coin production.
The Thrill of the Hunt
These five coins from the 1970s demonstrate that numismatic treasures can be found even in relatively recent coinage. From mint errors to commemorative varieties, each of these coins tells a unique story about American history, economics, and the minting process.
For collectors, the allure of these coins lies not just in their monetary value, but in the thrill of the hunt.
The possibility that a rare and valuable coin might be hiding in plain sight, mixed in with ordinary pocket change, adds an element of excitement to the hobby of coin collecting.
Moreover, these coins serve as tangible links to the past. Holding a 1972 Double Die Penny or a 1976 Bicentennial Quarter without the S mint mark connects us to the events and daily life of decades past.
It’s a reminder that history isn’t just found in museums or textbooks, but can be carried in our pockets and purses.
