1970 Washington Quarter Errors and Varieties: Identification Guide

The 1970 Washington quarter is one of many workhorse dates in the long-running eagle-reverse series that ran from 1932 through 1998, aside from the special 1776-1976 Bicentennial design. GetCoinHunt helps you search inventory from multiple coin dealers in one place, compare available examples, and create a wishlist alert when the right coin is not currently listed.

Design and history

The 1970 Washington quarter carries John Flanagan’s original design, first issued in 1932 for the bicentennial of George Washington’s birth. The obverse portrait is adapted from Jean-Antoine Houdon’s 18th-century bust of Washington. Except for the 1976 Bicentennial issue, the reverse shows a perched eagle with wings spread above a bundle of arrows and olive branches, per the U.S. Mint’s quarter history.

1970 issues: Denver circulation strikes and San Francisco proofs; no Philadelphia quarter was issued this year. Standard composition for this date is copper-nickel clad – an outer layer of 75% copper and 25% nickel bonded to a pure copper core – weighing nominally 5.67 grams. Denver strikes carry a D and San Francisco proofs carry an S; there is no Philadelphia issue to compare against.

Errors and varieties to know

No single mainstream key variety defines 1970. Specialist doubled dies exist, but each requires exact catalog attribution. No Philadelphia circulation quarter was issued. NGC’s VarietyPlus and PCGS CoinFacts are the standard references for attributing any claimed Washington quarter variety. A suspected feature that isn’t catalogued at one of those sources should be treated cautiously and priced conservatively, regardless of what a listing calls it.

The distinction matters when you’re comparing listings:

• A die variety repeats on every coin struck by the same altered or doubled die.
• A mint error results from something going wrong while one coin is made – for example, an off-center strike, a clipped planchet, or a coin struck on the wrong planchet.
• Post-mint damage happens after the coin leaves the press and is not a Mint-made feature at all.

Off-center strikes, clipped planchets, wrong-planchet strikes, missing clad layers, struck-through pieces, and similar production accidents can occur in principle on almost any date, including 1970. Each one is an individual manufacturing accident rather than a recurring variety, and it has to be diagnosed from the physical minting evidence on that specific coin – not assumed just because the date is old.

How to examine a 1970 Washington quarter

Begin with the date and mintmark, then use diffuse light and rotate the coin beneath it. A 5x to 10x loupe is enough for initial screening; more magnification won’t fix a soft photo or a weak strike. Compare both sides with a problem-free example from the same date and mint:

• Raised, rounded, repeatable features may come from the die.
• Incuse cuts, displaced metal, bright scrapes, flattened rims, and random dents point toward post-mint damage.
• Shelf-like flat doubling commonly indicates machine doubling, not a genuine doubled die.
• Filled or weak letters can result from grease, a worn die, wear, or a strike issue, so inspect the surrounding metal before assuming a variety.

If the coin appears off-metal or otherwise unusual, record its weight on a scale accurate to 0.01 gram, plus diameter, thickness, edge color, and orientation. A normal copper-nickel clad quarter is about 5.67 grams and shows a copper-colored core at the edge. Weight alone isn’t proof of anything – wear, corrosion, and manufacturing tolerances all matter. Photograph the whole obverse, whole reverse, edge, and any close-up detail under the same lighting before you request attribution from a specialist or a major grading service.

Buying considerations

Certified versus raw coins

A certified coin has been authenticated, graded, and sealed in a holder by a third-party grading service such as PCGS or NGC. A raw coin is sold without that certification. For an ordinary 1970 quarter in a typical circulated or common Mint State grade, certification usually isn’t worth the cost. It becomes worthwhile for a coin with a specifically attributed variety, a high Mint State or cameo proof grade, or any claim of a genuine mint error.

Before purchasing a certified coin:

• Confirm that the holder is from a recognized grading service.
• Verify the certification number through the grading service’s official website.
• Compare the holder’s photographs, when available, with the coin being offered.
• Remember that counterfeit grading holders also exist.

Understanding grades and condition

Most 1970 Washington quarters in the marketplace are common in circulated grades. Value concentrates in high-grade uncirculated examples with strong luster and no distracting marks, and in certified proofs. When comparing listings, look at:

• How clearly Washington’s portrait and the eagle’s feather detail are struck
• Remaining luster on uncirculated examples
• Marks, scratches, rim damage, or discoloration
• Whether the assigned grade is supported by a recognized grading service

Problem coins

Watch for listings that describe cleaned, improperly cleaned, scratched, bent, damaged, corroded, environmental damage, or altered surfaces. Problem coins are sometimes placed in holders with a details grade rather than a standard numerical grade – they can be a less expensive way to own the coin, but you should understand the stated problem and compare the asking price accordingly.

Suggested search terms and filters

Begin with a broad search: “1970 Washington quarter.”

Then narrow the results with terms that reflect your collecting goal:

• By mint mark: as applicable for 1970 – Denver circulation strikes and San Francisco proofs; no Philadelphia quarter was issued this year.
• By grade: circulated, MS60-MS70, PR60-PR70
• By certification: PCGS, NGC, or “certified Washington quarter”
• By feature: describe any claimed variety by its specific attribution (for example, an FS- number from a recognized reference), not by an informal nickname alone

Availability and pricing notes

1970 Washington quarters are common overall, and ordinary circulated examples are inexpensive. Listings and asking prices don’t necessarily represent completed-sale values – compare multiple examples, consider each coin’s grade and surface quality, and review recent market information before purchasing.

GetCoinHunt does not guarantee that every listing is authentic, accurately graded, or fairly priced. Authentication, grading, pricing, return policies, and fulfillment remain the responsibility of the dealer or marketplace offering the coin.

Frequently asked questions

Is the 1970 Washington quarter rare or valuable?

No. Specialist doubled dies exist, but no single mainstream key variety defines the year, and no Philadelphia quarter was struck. Most circulated examples are common and inexpensive; value concentrates in high-grade uncirculated coins, certified proofs, and any coin with a specifically attributed, certified variety or error.

Are there any officially recognized varieties for the 1970 Washington quarter?

No single mainstream key variety defines 1970. Specialist doubled dies exist, but each requires exact catalog attribution. No Philadelphia circulation quarter was issued.

How do I tell a die variety from a mint error or damage?

A die variety repeats on every coin struck from the same die and shows raised, rounded, repeatable detail. A mint error is an individual manufacturing accident, such as an off-center strike or a wrong planchet. Post-mint damage happens after the coin leaves the Mint and is not a genuine Mint-made feature.
