Rare 1974 Penny Error List & Value

1974 Penny D/S Over Mintmark Error

This error occurred when San Francisco dies were reassigned to Denver Mint operations due to die shortages. The original “S” mintmark was partially ground away before the “D” was punched over it.

Remnants of the underlying “S” remain visible under magnification. This creates a distinctive overlapping appearance that collectors prize.

Values for this variety typically range from $15 to $500 depending on condition. Higher grade examples with clear visibility of both mintmarks command premium prices.

To identify this error, examine the mintmark area carefully with at least 10x magnification. Look for traces of curved lines beneath or around the “D” mintmark.

1974 Penny Aluminum Experimental Error

The U.S. Mint struck over 1.5 million aluminum pennies in 1974 as an experimental cost-saving measure. These coins were never officially released into circulation.

Made from 96% aluminum with trace metals, these pennies weigh only 0.93 grams. Regular copper pennies weigh approximately 3.11 grams.

Estimated values range from $250,000 to $2 million for authenticated examples. However, owning one is technically illegal since they remain government property.

If you find a silvery 1974 penny, weigh it immediately. The dramatic weight difference is your first clue to potential authenticity.

1974 Penny Large Date Small Date Error

The Mint created two different master dies during 1974 production. The Large Date (Type I) appeared first, followed by the Small Date (Type II) with lower relief.

Key identification points include the triangle inside the “4″ digit. On Small Date varieties, this triangle appears taller than it is wide.

Both varieties exist for Philadelphia, Denver, and San Francisco mints. Proof coins were only struck with Large Date dies.

Values range from $1 to $25 for most examples. Higher grade specimens with exceptional eye appeal bring stronger prices at auction.

1974-D Penny Doubled Die Obverse Error

The 1974-D doubled die obverse shows distinct doubling on design elements. This occurs when the die receives multiple impressions during the hubbing process.

Look for doubling in the date, lettering, and Lincoln’s portrait details. The effect creates a shadow-like appearance on affected areas.

Values typically range from $50 to over $200 for confirmed examples. Condition and the strength of doubling significantly impact final prices.

Examine your coins under good lighting with magnification. True doubled dies show consistent, uniform doubling rather than mechanical damage.

1974-S Penny Die Break Cud Error

Die breaks occur when pieces of the die crack or break away during production. This creates raised areas or missing design elements on struck coins.

Cuds appear as raised, blob-like formations typically near the rim. Each die break creates a unique pattern making affected coins one-of-a-kind.

Values range from $10 to $184 depending on size and location. Larger, more prominent cuds in visible areas command higher premiums.

Examine the rim and field areas carefully for irregular raised metal. Die breaks vary dramatically in appearance and collector appeal.

1974-S Penny Doubled Mintmark Error

Two different “S” mintmark punches were used during 1974 production. The transition between punches created varieties with distinctive characteristics.

The earlier punch shows a horizontal line in the lower loop. The later punch displays a bulge on the outside upper curve.

Some specimens show evidence of repunched mintmarks where multiple strikes occurred. Values range from $15 to $100 for notable examples.

Compare your mintmark against reference images to identify the specific variety. Subtle differences require careful examination under magnification.
