Understanding the History of the 1958 Franklin Half Dollar
The 1958 Franklin Half Dollar is part of a beloved series that ran from 1948 to 1963. It features the founding father Benjamin Franklin on the obverse and the Liberty Bell on the reverse. If you are trying to identify yours, using a top coin identifier app can help you confirm the date and mint mark.
This silver coin was designed by John R. Sinnock, whose initials can be found on Franklin’s shoulder. At the time of its release, the design was controversial because some people felt putting a non-President on a coin was odd, but Franklin’s legacy as a printer, scientist, and statesman eventually won the public over.
In 1958, the United States was in the midst of a post-war economic boom, and these halves were everyday pocket change. Today, however, most have been melted down for their silver content or reside in private collections. If you’re unsure if your coin is a common “junk silver” piece or a treasure, the CoinKnow app can provide an instant assessment based on visual traits.

How Much Silver is in a 1958 Franklin Half?
Before looking at collector demand, it is vital to understand the intrinsic value of the 1958 Franklin Half Dollar. Every coin produced in 1958 consists of 90% silver and 10% copper. This means that even if the coin is scratched, dented, or heavily worn, it will never be worth less than its weight in silver.
The silver content totals approximately 0.3617 troy ounces. To find the “melt value,” you simply multiply the current spot price of silver by 0.3617. When silver prices rise, the value of even the roughest 1958 halves goes up accordingly.
For many beginners, checking the 1958 Franklin Half value against current silver market trends is the first step. While silver provides a “floor” for the price, the “ceiling” is determined by rarity and condition. Professional tools like CoinKnow can track these market fluctuations for you in real-time.

Identifying Mint Marks: Philadelphia vs. Denver
In 1958, Franklin Half Dollars were struck at two different mint facilities: Philadelphia and Denver. Identifying which one you have is crucial for determining its market price. You can find the mint mark on the reverse side of the coin, located just above the Liberty Bell’s yoke.
If there is no letter present, the coin was minted in Philadelphia. These are often simply referred to as “1958 P” halves. If there is a small “D,” it was struck in Denver. In 1958, Denver produced significantly more coins—about 23.9 million—compared to Philadelphia’s 4 million.

Surprisingly, despite the lower mintage, the Philadelphia issues are often more affordable in lower grades because they were less frequently saved by the public. You can check the specific 1958 Franklin Half high-grade prices to see how the mint mark influences value at the top tier of the market.
| Mint Location | Mint Mark | Mintage Quantity |
|---|---|---|
| Philadelphia | None | 4,042,000 |
| Denver | D | 23,962,412 |
| Proof (Philly) | None | 875,652 |
Grading and the “Full Bell Lines” (FBL) Factor
For serious collectors, the “grade” of the coin is everything. A coin that looks shiny and new (Mint State) is worth significantly more than one that was used to buy groceries in the 50s. If you have an uncirculated coin, look closely at the bottom of the Liberty Bell.
“Full Bell Lines” (FBL) is a designation given to Franklin Half Dollars that show full, uninterrupted horizontal lines near the bottom of the bell. Because the dies often wore down, many coins have blurry or “mushy” lines. An FBL coin can command a massive premium.

If you are unsure if your coin meets this criteria, the CoinKnow app’s high-resolution grading guides can help you spot the difference. A 1958-D with Full Bell Lines in MS66 grade can sell for several hundred dollars, while a standard MS66 might only bring $60.
| Grade | Standard Price | Full Bell Lines (FBL) Price |
|---|---|---|
| MS64 | $40 | $65 |
| MS65 | $75 | $150 |
| MS66 | $180 | $550 |
| MS67 | $1,200 | $12,500+ |
1958 Proof Franklin Half Dollars
In addition to regular business strikes, the Philadelphia Mint produced 875,652 Proof coins in 1958. These were specifically made for collectors and possess a mirror-like finish. They were sold in “Proof Sets” and usually have much higher detail than standard coins.
Within the Proof category, collectors look for “Cameo” and “Deep Cameo” effects. This is where the frosted portrait of Franklin stands out sharply against the shiny background. A 1958 Proof with a Deep Cameo (DCAM) finish is exceptionally rare.
Standard 1958 Proofs generally sell for $30 to $50. However, if you find one that looks almost like a black-and-white photograph because of the contrast, you could be looking at a coin worth $500 to $1,000. Always handle these by the edges to avoid leaving fingerprints on the delicate surfaces.

Key Errors to Look For
While the 1958 series isn’t known for many “major” errors, there are some subtle varieties that can increase the value. The most common things to look for are “Double Dies,” where the coin was struck twice by the machinery, leaving a faint ghost-like image of the letters or numbers.
Look specifically at the lettering on the reverse (like “UNITED STATES OF AMERICA”) or the date on the front. If you see clear doubling with the naked eye, your coin could be worth twice its listed value or more.
Other errors include “die cracks” or “lamination errors,” where the metal of the coin appears to be peeling. While these aren’t as valuable as a double die, they are still unique pieces of history that collectors enjoy. Using a magnifying glass or a high-zoom camera app is the best way to inspect these small details.
| Error Type | Estimated Added Value |
|---|---|
| Minor Double Die | +$20 to +$50 |
| Major Die Crack | +$10 to +$30 |
| Off-Center Strike | $100 – $500 (depending on %) |
