Imagine finding a quarter in your loose change that could be worth thousands of dollars. That’s the case with the rare 1970-D Washington quarter, which, due to specific minting errors and unique characteristics, has become a highly valuable find among coin collectors. Here’s a closer look at what makes this quarter special, the key factors affecting its value, and how to preserve it.
Characteristics of the 1970 Quarter
The 1970-D quarter is part of the U.S. Mint’s Washington quarter series, known for its classic design featuring George Washington on the front and an eagle on the reverse. Minted in Denver, this coin has a small “D” mint mark on the right side of Washington’s ponytail, signifying its place of origin.
The high value of the 1970-D quarter stems primarily from a rare minting error. Some quarters from this year were accidentally struck on dime planchets instead of quarter planchets. These error coins are lighter, thinner, and slightly off in appearance compared to standard quarters. This mistake has made these coins incredibly rare and highly sought after among collectors, adding to their value.
Value of the 1970 Quarter and Key Factors
The market value of a 1970-D quarter depends on a few key factors: the coin’s condition, grade, and whether it has the rare minting error. Generally, a standard 1970-D quarter in good condition may only be worth a few dollars. However, those in near-perfect condition, such as Mint State (MS) 67, can reach values around $65.
The rare 1970-D quarters with the error are particularly valuable. Those struck on dime planchets and found in high-grade conditions (up to MS-69) have fetched prices of up to $15,000 at auction. Such quarters are prized for their rarity and unique error, with collectors eager to add these rare finds to their collections.
How to Preserve Valuable Coins
If you’re fortunate enough to discover a 1970-D quarter, proper preservation is essential to maintain its value. Follow these key tips to ensure your coin stays in the best possible condition:
- Handle Carefully: Always hold coins by their edges to avoid transferring oils from your hands to the coin’s surface, which can damage the finish. Using cotton gloves can further protect the coin.
- Avoid Cleaning: Cleaning a valuable coin can actually reduce its value. Natural oxidation, or “patina,” is often appreciated by collectors as it shows authenticity. Cleaning can scratch or alter the coin’s surface, leading to a decrease in its grading.
- Store Properly: Place valuable coins in individual holders or clear acrylic cases to keep them protected from dust, moisture, and other contaminants. Secure cases will help prevent accidental wear over time.
- Keep in a Controlled Environment: Avoid storing coins in areas with fluctuating temperatures or high humidity, as these conditions can cause tarnishing or corrosion. A cool, dry place is ideal for long-term preservation.
By taking these simple steps, you can maintain the condition of your coins and preserve their potential market value for years to come.
