The history of the John Adams dollar
The John Adams dollar was released on May 17, 2007 along with the dollars of Presidents George Washington, Thomas Jefferson and James Madison, all belonging to the “Presidential Dollars” series.
What a dollar John Adams looks like
The obverse of the coin features the portrait of President John Adams on the right with his name in capital letters above it and the legend “2nd President 1797-1801” at the bottom of the bust. Its designer was Joel Iskowitz, the engraver of the obverse was Charles L. Vickers – the initials of both can be seen on the President’s shoulders, JI on the left side and CLV on the right.
The reverse features the Statue of Liberty on the left with the value $1.00 and the legend “UNITED STATES OF AMERICA” around it starting at 6 o’clock. The engraver/engraver of the reverse was Don Everhart and also has his initials on the reverse under the hand of the Statue of Liberty.
The date (2007), the mintmark letter and the legends “IN GOD WE TRUST” and “E PLURIBUS UNUM” are engraved on the edge of the coin.
At this point it seems pertinent to explain that due to the way of minting the edge the legends can be oriented towards the obverse or towards the reverse. This is what the company PCGS classifies as Position A and Position B.

How many John adams dollars were manufactured and in what qualities?
The John Adams dollar series were produced in the three most famous mints of the United States of America:
- Mintmark Philadelphia (P): 112,420,000 units.
- Mintmark Denver (D): 112,140,000 regular strike and 895,628 satin finish (special strike) units.
- Mintmark San Francisco (F): In different finishes. 3,965,989 units only in proof quality.
| Units | Regular | Proof | Grades | Value |
| Philadelphia | 112,420,000 | MS63-MS66 | $6 – $20 | |
| Philadelphia | 895,628 | SF64-SF69 | $60 – $100 | |
| Denver | 112,140,000 | MS63-MS69 | $5 – $89 | |
| Denver | 895,628 | SF64-SF69 | $45 – $95 | |
| San Francisco | 3,965,989 | PR68-PR70 | $10 – $300 |
As you can see in the table the John Adams dollar is not a difficult coin to obtain in high grades for a few hundred dollars, due in part to the high number of pieces produced.
Proof copies of San Francisco were sold in sets of 4 proof copies of the dollars of George Washington, John Adams, Thomas Jefferson and James Madison.
The importance of Regular Strikes
The Philadelphia and Denver mints produced coins in MS63 and MS64 average states for circulation of the so-called Regular Strikes.
Due to the large number of units produced and the average grades, the option of looking for MS66 and higher grades is the best one to collect or invest in these pieces.
It is always best to try to get the highest quality John Adams dollar we can afford as they will be scarcer and more valuable pieces.
5 Most important john adams dollar mistakes
By carrying out a more detailed study of the market we find a series of very valuable errors of the John Adams dollar that we need to detect and classify.
Types of relevant errors
Missing Edge Lettering
By mistake some John Adams dollars were released without having the edge of the coin minted (as was the case with its predecessor the George Washington dollar).
We remember that on the edge of these pieces appeared the date, the mint mark and two mottos: “IN GOD WE TRUST” and “E PLURIBUS UNUM”.
Within this error we find John Adams dollars without the minting of the legend “IN GOD WE TRUST”. John Adams dollars with this error are known as Godless dollars or also as dollars with plain edge dollar errors.
The estimate of John Adams minted with this error is 12,000 units.
Doubled Edge Lettering
If in the Godless dollar error there was a lack of edge lettering in the error known as “doubled edge lettering” just the opposite happened, that is to say, that the officials in charge of the minting to make sure that the edges were well minted came to pass some copies twice through the press minting the edge.
It is also known as the typewriter edge error.
Inverted Doubled Edge Lettering
This error occurs as a derivation of the “Doubled Edge Lettering” error, because when the coin was passed twice through the edge engraving machine the legends were engraved in opposite directions, i.e. the first time the coin was positioned with the obverse side up and the second time with the obverse side down, for example.
Lettered Blank Planchet
In this type of error, one of the rarest and scarcest, occurred when the coin went directly through the edge engraving machine and they forgot to mint it in the press with the obverse and reverse dies, so the coin blanks but with a perfectly engraved edge.
What are the most valuable John Adams dollar mistakes?
With the above explained let’s see below some prices reached by the John Adams dollar starting with the highest amounts.
#1 (2007)-? Double Struck on an Aluminum Feeder Finger Fragment – MS64 PCGS – $3,335
Curious mintage or proof of the 2007 John Adams dollar in aluminum that due to its shape it is not possible to detect the mint, nor the year although we know that it must be 2007. It has a weight of 9 grams despite missing more than 60% of the coin.
Auctioned in October 2009 for $3,335 (Source).
(2007)-? Struck Twice on an Aluminum Feeder Finger Fragment – MS64 PCGS – $2,300
Another aluminum example was auctioned in September 2009 and went for $2,300 (Source).
#2 2007-? Plain Edge, Struck Seven Times, Strikes 3 Through 40% Off Center, Missing Edge Lettering – MS66 PCGS – $3,120
In addition to not having an engraved edge, this coin has 7 mintages. A first mintage centered and correct and the remaining six mintages with a 40% displacement without any rotation of dies between the first mintage and the remaining ones.
It reached $3,120 in November 2017 (Source).
#3 Missing Edge Lettering, Double Struck, Second Strike 20% Off Center & 5% – MS66 PCGS – $1,860
This is a double minted piece with offset and poorly trimmed with an unengraved edge, which is why we do not know the mint, which was sold in this same year 2021 for $1,860 (Source).
#4 2007-P Triple Struck, Broadstruck, and Missing Edge Lettering- MS65 PCGS – $1,380
In September 2009 a John Adams dollar from the Philadelphia mint was sold with 3 types of errors:
- Triple mintage (as can be seen in the photo with the detail of the lot that we reproduce below and we point out the triple mintage that is more pronounced in the letters of the legend),
- Broadstruck and
- Missing Edge Lettering.
It was the John Adams dollar 2007 of Philadelphia of the type Position A, according to the classification of PCGS, which was the certifying company.
The price reached for this curious specimen that combined in the same coin 3 different types of errors was $1,380. Here you can see the link to the auction.
#5 (2007)-? Multiple Strikes, 33% Double clip, Missing Edge Lettering – MS63 PCGS – $1,320
This trimmed John Adams dollar has at least 5 mint marks or strikes. For the missing parts it is not possible to determine the mint or the year, although we know for sure that it must be from 2007 for everything we have seen in this article.
It is graded by PCGS as MS63 and was auctioned off at auction for $1,320 in September 2018 (source).
Is a John Quincy Adams dollar coin worth anything?
A John Quincy Adams dollar coin is a modern circulating coin produced by the United States Mint from 2007 to 2008 as part of the Presidential $1 Coin Program. While these coins are not particularly rare, they have some value to collectors depending on their condition and whether they have any errors or varieties.

Yes, there is a John Adams $1 coin. It was produced as part of the Presidential $1 Coin Program by the United States Mint from 2007 to 2008. The program was intended to honor each U.S. president by featuring their likeness on circulating $1 coins. John Adams was the second president of the United States, serving from 1797 to 1801. His coin was released in 2007, the same year as the first coin in the series, which featured George Washington. Like all Presidential $1 coins, the John Adams $1 coin has the standard obverse design of the Statue of Liberty and the required inscriptions. The coin’s reverse design features John Adams and the inscriptions “2nd President” and “1797-1801”.
How much is a 1797 dollar coin worth?
The 1797 dollar coin, also known as the Draped Bust dollar, is a rare and valuable coin. Its value depends on various factors, including the coin’s condition, rarity, and history.
If you have a genuine 1797 Draped Bust dollar coin, its value can range from tens of thousands to hundreds of thousands or more, depending on its condition and other factors. For example, a well-preserved 1797 Draped Bust dollar coin in uncirculated condition can be worth several hundred thousand dollars or more. A coin in poor condition or with significant damage may be worth much less.
