Most Kennedy half dollars are worth only face value. But a rare 1972-D Kennedy Half Dollar missing the “FG” initials has become a valuable mint error, with some examples selling for $150 to $250 or more.
This hidden error is easy to overlook, yet collectors actively search for it. Here’s a step-by-step guide to help you identify this valuable coin. 
Step 1: What Does “Missing FG” Mean?
On normal Kennedy half dollars, you’ll find the small initials “FG” on the reverse side of the coin.
These initials represent Frank Gasparro, the designer of the Kennedy Half Dollar.
The initials are located:
- On the reverse (back) of the coin
- Between the eagle’s tail feathers and right leg
If these initials are completely missing, the coin becomes a valuable error variety.
Step 2: Why This Error Happened
This mint error was caused by excessive die polishing during production.
When mint workers polished the dies, they accidentally removed the small “FG” initials. As a result, some coins were struck without the designer’s mark.
Because this was not intentional, these coins are considered genuine mint errors and highly collectible.
Step 3: How to Identify the 1972-D Missing “FG” Half Dollar
Follow this simple checklist:
Check the Date
- Must be 1972
Check the Mintmark
- Look for the “D” mintmark
- Located on the front (obverse) below Kennedy’s portrait
Check the Reverse for “FG”
Look closely at the area near the eagle’s right leg.
- Rare coin: No “FG” initials visible
Normal coin: “FG” initials clearly present
Using a magnifying glass makes this much easier.
Step 4: Estimated Value Based on Condition
The coin’s condition significantly affects its value.
| Condition | Estimated Value |
|---|---|
| Fine (F–VF) | $40 – $70 |
| Extremely Fine (XF) | $80 – $120 |
| Uncirculated (MS) | $150 – $250+ |
Certified high-grade examples often bring the highest prices.
Step 5: What To Do If You Find One
If you believe you found this error coin, take these important steps:
Protect the Coin
- Store in a protective holder
- Avoid scratches or damage
Never Clean the Coin
Cleaning reduces collector value significantly.

Submit your coin to trusted grading services such as:

Professional grading increases value and confirms authenticity.
