1945 Mercury Dime Errors, Key Dates, Varieties and Value

The 1945 Mercury dime was struck at Philadelphia, Denver and San Francisco, and the San Francisco issue includes the widely collected 1945-S Micro S variety. 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 1945 Winged Liberty Head dime – the coin’s official name, though collectors commonly call it the “Mercury” dime because Liberty’s winged cap was mistaken for the Roman god – was struck at Philadelphia, Denver and San Francisco. Adolph A. Weinman designed both sides: the obverse depicts Liberty wearing a winged Phrygian cap, intended to symbolize freedom of thought, and the reverse combines a fasces, representing unity and authority, with an olive branch for peace. Weinman’s monogram appears on the obverse; D and S mint marks, when present, appear on the reverse near the lower-left portion of the fasces, while Philadelphia coins carry no mint mark.

The series is 90% silver and 10% copper throughout, with a standard weight of 2.50 grams, a diameter of 17.90 mm, and a reeded edge, per PCGS CoinFacts.

Errors and varieties to know

The 1945-S Micro S is one of the three major varieties PCGS treats as part of the standard Mercury dime canon, alongside the 1942/1 and 1942/1-D overdates. Its mint mark is distinctly smaller than the normal 1945-S punch. Compare the entire S – height, width, loops, and placement – with verified reference photographs rather than judging by size alone. It is collectible but not extremely rare: PCGS notes that more than a third of submitted 1945-S dimes are Micro S examples. The Philadelphia 1945 is also famously difficult to find with fully split reverse bands, but Full Bands is a strike designation, not a variety.

See PCGS’s write-up on the 1945-S Micro S for photographs and diagnostic detail.

How to examine a 1945 Mercury dime

Begin with the date and mint mark under one steady, directional light, then rotate the coin beneath it. Compare both sides with a problem-free example of the same date and mint:

• A genuine punched or repunched element is raised and belongs to the die; a scratch is incuse and may push metal along its edge.
• True doubled-die or overdate detail is rounded and repeats in the exact locations documented for that die; mechanical doubling is flat and shelf-like.
• Die deterioration creates swelling or erosion, not a clean second digit.
• A true off-center strike omits part of the design and leaves an unstruck crescent; a clipped planchet shows compatible rim and edge effects; a broadstrike expands outside the collar; strike-throughs leave smooth depressions or transferred texture.

For mint marks, examine the surrounding field for seams, depressions, discoloration, or tooling – these can expose an added or moved mint mark. Surface continuity matters most on valuable dates. A genuine coin can still be harshly cleaned, scratched, or repaired, which reduces value even when the date and mint mark are authentic.

Bent, squeezed, plated, acid-treated, or dryer-damaged coins are altered after striking and are not Mint errors. If the coin appears off-metal, record its weight on a scale accurate to 0.01 gram alongside diameter, thickness, edge color, and orientation, and compare against the standard 2.50-gram, 17.90 mm, reeded-edge specification. For a valuable-looking discovery, seek attribution from a specialist or certification from a major grading service before treating any price claim as reliable.

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.

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.

For a claimed 1945-S Micro S, compare the coin against certified, attributed examples – since more than a third of submitted 1945-S dimes qualify, it is worth confirming rather than assuming either way.

Understanding grades and condition

Wear on a Mercury dime first appears in Liberty’s hair and on the high central reverse. “Full Bands” describes complete separation in the horizontal bands around the center of the fasces on qualifying Mint State coins – it is a strike-quality designation, not a die variety or an error, and NGC’s grading discussion explains it in more detail. A Full Bands premium can be substantial for dates that are normally weakly struck, but the coin must also be uncirculated and meet the grading service’s specific definition.

When comparing listings, look at:

• How clearly the date, mint mark, and design details are struck
• Remaining luster on uncirculated examples
• Marks, scratches, rim damage, or discoloration
• Whether the assigned grade – and any Full Bands designation – is supported by a recognized grading service

Do not estimate value from a dramatic asking price. Match the precise date, mint, attribution, and grade to completed auction results before assuming a listing reflects fair market value.

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 date, but you should understand the stated problem and compare the asking price accordingly.

Suggested search terms and filters

Begin with a broad search: “1945 Mercury dime,” “1945-D Mercury dime,” or “1945-S Mercury dime.”

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

• By mint mark: no mark (Philadelphia), D, or S
• By grade: circulated grades through MS60-MS70, and Full Bands where applicable
• By certification: PCGS, NGC, or “certified 1945 Mercury dime”
• By feature: “1945-S Micro S”

Useful filters may include grade, grading service, price range, dealer, certification status, and problem-free versus details-graded coins. Avoid filtering so narrowly that legitimate listings disappear – dealers may format dates, grades, and mint marks differently.

Availability and pricing notes

Coin availability can change quickly, especially for scarcer dates and grades. Listings and asking prices do not 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

What does the 1945 Mercury dime look like?

The obverse shows Liberty facing left wearing a winged Phrygian cap, a design intended to symbolize freedom of thought. The reverse shows a fasces – a bound bundle of rods representing unity and authority – crossed with an olive branch for peace. Both sides were designed by Adolph A. Weinman.

Is there a recognized error or variety for 1945?

Yes. The 1945-S Micro S is one of the three major varieties PCGS treats as part of the standard Mercury dime canon. Its mint mark is distinctly smaller than the normal 1945-S punch. It is collectible but not rare – PCGS notes more than a third of submitted 1945-S dimes qualify.

What does “Full Bands” mean?

Full Bands refers to complete separation in the horizontal bands around the center of the fasces on the reverse. It is a strike-quality designation used mainly for qualifying Mint State coins and is not a die variety or an error.

Is a 1945 Mercury dime valuable?

Ordinary 1945 dimes from all three mints are common and trade close to silver value in worn grades. A confirmed 1945-S Micro S carries a modest collector premium, and a Full Bands 1945 Philadelphia dime is notably scarce in that strike designation.
