What is a 2006-D South Dakota Quarter worth?
Worn examples are worth face value and can be spent. Keep it only if it looks uncirculated or shows a known variety.
What would make yours worth more:
- Uncirculated condition with full original luster
- A die variety or minting error
For market prices, check recent sold results for certified coins in the same grade.
Quick answers
- Is the 2006-D South Dakota Quarter rare?
- Not by date: 266 million were struck. A sharp uncirculated coin or a known variety is what makes one special.
- Is the 2006-D South Dakota Quarter silver?
- No. It's copper core clad in 75% copper / 25% nickel. Quarters dated 1964 and earlier are 90% silver.
- Where is the mint mark on a 2006 50 State Quarter?
- On the obverse, to the right of Washington's ponytail (P, D or S). On this coin the mark is D, for Denver.
- How many 2006-D South Dakota Quarter coins were made?
- 265,800,000.
What to check on your 2006-D
- Make sure the mint mark really is a D. A worn or filled mark can be misread. It's what separates your coin from the 2006-P (245 million made).
- Proof or circulation strike? A proof has mirror-like fields and frosted design details and was sold to collectors, not released in change. The 2006-S South Dakota Quarter Proof (2,882,428 made) is the one to compare with.
- A face that's fully copper colored could be a missing clad layer error. Patchy discoloration is usually damage.
- Judge the grade under good light. State quarters are judged mainly on luster and contact marks. Look for die varieties and errors, which carry the real premiums in this series.
With 266 million made, the 2006-D still turns up in everyday change. Keep yours only if it looks uncirculated or shows a variety; otherwise it's worth face value.
The story of the 2006-D South Dakota
Denver made 265,800,000 of the South Dakota quarter. That was the smallest Denver run of the 5 designs issued in 2006, so it's the one from that year you're least likely to find in change.
Philadelphia struck a similar number of the same design (245 million), so neither mint's version is much harder to find.
Across the whole program it sits 20th of 50 Denver designs by mintage, where the scarcest is Oklahoma at 195 million.
Elsewhere in US coinage in 2006
The Jefferson nickel received a new forward-facing portrait of Jefferson and the original Monticello reverse returned.
How to recognize it
The South Dakota design
Mount Rushmore National Memorial appears with a ring-necked pheasant, the state bird, flying above it. Heads of wheat border the design. The memorial in the Black Hills features the faces of Presidents Washington, Jefferson, Theodore Roosevelt and Lincoln, carved between 1927 and 1941 under the direction of Gutzon Borglum. South Dakota became a state in 1889. Its quarter was the last released in 2006.
The 50 State Quarter design
To make room for each state design, the obverse was rearranged: UNITED STATES OF AMERICA, LIBERTY, IN GOD WE TRUST and QUARTER DOLLAR all moved to the side with Washington's portrait. The reverse shows the state's design with its name, the year it joined the Union or ratified the Constitution, the year of issue and E PLURIBUS UNUM. The mint mark is to the right of Washington's ponytail.
