The U.S. Mint’s 50 State Quarters Program, running from 1999 to 2008, introduced unique designs for each state, captivating both the public and collectors.

While most of these quarters hold their face value, certain rare variations and errors have made specific coins highly sought after, with some fetching prices up to $10,500.

Let’s delve into the top seven state quarters that could significantly enhance your collection’s value.

1. 1999-P Delaware State Quarter (Experimental Planchet)

Estimated Value: Up to $4,888

Notable Feature: Minted on an experimental alloy planchet.

The inaugural coin of the series, the Delaware quarter, features Caesar Rodney’s historic ride. A limited number were struck on experimental planchets, leading to a distinct appearance and increased value among collectors.

2. 2004-D Wisconsin State Quarter (Extra Leaf Error)

Estimated Value: Up to $6,000

Notable Feature: An extra leaf on the corn stalk, either pointing up or down.

This error resulted in two variations: the “High Leaf” and “Low Leaf.” These anomalies have made the Wisconsin quarter particularly desirable, with pristine specimens commanding high prices.

3. 2005-P Minnesota State Quarter (Double Die Error)

Estimated Value: Up to $3,000

Notable Feature: Extra trees due to a doubling error.

Some Minnesota quarters exhibit a doubling effect, resulting in the appearance of extra trees. This minting error has made these coins valuable, especially in higher grades.

4. 2000-P South Carolina State Quarter (Off-Center Error)

Estimated Value: Up to $2,500

Notable Feature: Off-center strike.

Off-center errors occur when the coin is not properly aligned during minting. The South Carolina quarter with such an error is a rare find and highly valued by collectors.

5. 2000-P Massachusetts State Quarter (Broadstrike Error)

Estimated Value: Up to $2,000

Notable Feature: Missing the reeded edge due to a broadstrike error.

A broadstrike error happens when the coin is struck outside the collar, causing it to spread out and lose its reeded edge. The Massachusetts quarter with this error is a notable rarity.

6. 2005-P Kansas State Quarter (“In God We Rust” Error)

Estimated Value: Up to $1,500

Notable Feature: The motto “In God We Trust” appears as “In God We Rust” due to a filled die error.

This error, caused by grease filling the die, led to the missing “T” in “Trust,” creating a unique and collectible variation.

7. 2000-P New Hampshire State Quarter (Off-Center Error)

Estimated Value: Up to $1,000

Notable Feature: Off-center strike.

Similar to the South Carolina quarter, the New Hampshire quarter with an off-center error is a rare and valuable find for collectors.
