The 1978 Roosevelt Dime with no mint mark is worth anywhere from face value in heavily worn condition to $5 or more in uncirculated grades — and a few exceptional examples have sold for significantly higher at auction. If you found one in your change jar or an old coin collection, you’re in the right place to find out exactly what it’s worth.

What Is the 1978 Roosevelt Dime with No Mint Mark

The 1978 Roosevelt Dime with no mint mark was struck at the Philadelphia Mint. During this era, Philadelphia did not place a “P” mint mark on dimes — that practice didn’t begin until 1980. So if your 1978 dime has no mint mark on the obverse near Roosevelt’s portrait, that simply means it came from Philadelphia, not that something is missing or unusual.

This coin is made of a copper-nickel clad composition — 75% copper and 25% nickel — which replaced silver in dimes after 1964. The Philadelphia Mint produced over 663 million of these dimes in 1978, making them extremely common in circulated grades.

For most people, a well-worn 1978 P dime is worth exactly 10 cents. But the story gets more interesting when you start looking at higher-quality examples.

1978 Roosevelt Dime Value by Grade

The condition of your coin — known as its grade — is everything when it comes to value. A coin graded MS-65 or higher can be worth real money, especially if it has strong luster and sharp strike details.

What Makes Some 1978 Dimes Worth More

Most 1978 Philadelphia dimes are common — but a few stand out. The key factors that drive value up are eye appeal, full bands designation, and overall surface quality.

The “Full Bands” (FB) designation refers to the torch bands on the reverse of the coin being fully struck and sharply defined. Coins certified as MS-65 FB or higher by PCGS or NGC can sell for multiples of a standard uncirculated example.

CoinKnow is a great tool if you want to quickly assess whether your coin might qualify for a premium grade. It walks you through the details to look for — including strike quality and luster — so you’re not guessing.

Error coins also carry a premium. Look for doubled die obverse errors, off-center strikes, or clipped planchet errors. These are rare on 1978 dimes but not unheard of, and even minor errors can make a coin worth $20–$50 or more.

1978 Dime No Mint Mark vs Other 1978 Dimes

In 1978, the U.S. Mint produced Roosevelt Dimes at two facilities: Philadelphia (no mint mark) and Denver (D mint mark). There was no San Francisco business strike that year, though proof coins were made for collector sets.

The Denver dime had a mintage of about 282 million — notably lower than Philadelphia. This can sometimes mean slightly higher premiums for high-grade Denver examples, but both are common in lower grades.

If you want a full breakdown of the complete 1978 dime value including all mint marks and varieties, that resource covers everything from circulated grades to top-pop auction records in detail.

The proof dimes from 1978, struck at San Francisco with an “S” mint mark, were not released into circulation and are only found in proof sets. These have their own separate value range.

How to Get the Best Price for Your 1978 Roosevelt Dime

If your coin grades MS-65 or higher, consider having it certified by PCGS or NGC before selling. A slab adds credibility and can significantly increase what a buyer is willing to pay.

For circulated examples, selling in bulk as part of a dime roll or lot is usually more efficient than trying to sell individual coins. Coin dealers, eBay, and local coin shows are all reasonable options.

CoinKnow can also help you understand recent sold prices so you walk into any sale knowing what your coin is actually worth on the current market — not just what someone hopes to pay.

Frequently Asked Questions

Q: Is a 1978 dime with no mint mark rare?
A: No, it is not rare. The Philadelphia Mint produced over 663 million 1978 Roosevelt Dimes. The lack of a mint mark is normal for this year, since Philadelphia did not use the “P” mark on dimes until 1980. Most examples are worth only face value unless in high uncirculated grades.

Q: Could my 1978 no mint mark dime be silver?
A: No. All 1978 Roosevelt Dimes — regardless of mint mark — are clad coins made of copper-nickel. Silver dimes were last minted for circulation in 1964. The easiest way to check is to look at the edge: a clad dime shows a visible copper stripe, while a silver dime has a solid silver edge.

Q: What is a 1978 Roosevelt Dime worth in MS-67?
A: A 1978 Philadelphia dime graded MS-67 by PCGS or NGC can be worth $25 to $100 or more, depending on eye appeal and whether it carries the Full Bands designation. At MS-67 FB, values can push even higher if the coin is a top-pop example with no competition on the registry.
