which american coins are made of silver

Based on the information provided, the silver content of American coins is primarily determined by their denomination and the year they were minted. A significant number of U.S. coins produced for general circulation contained silver up until the mid-1960s. For common denominations, dimes, quarters, and half dollars minted in 1964 or earlier are composed of 90% silver. Similarly, silver dollars minted in 1935 or before also consist of 90% silver. These coins are often referred to as "junk silver," a term that relates to their silver bullion value rather than any numismatic or collectible value. After 1964, the silver content in circulating coins was reduced or eliminated. However, certain coins produced for a limited time still contained silver, though at a lower purity. Kennedy Half Dollars minted between 1965 and 1970 contain 40% silver. Some Eisenhower Dollars, specifically those produced from 1971 to 1976, were also made with 40% silver. Another notable example is the "War Nickel," minted from 1942 to 1945, which contains 35% silver. In addition to historical currency, the U.S. Mint produces modern bullion coins specifically for collectors and investors. These coins have a much higher purity. The American Silver Eagle, produced from 1986 to the present, and the America the Beautiful series (2010-2021) are both made of 99.9% fine silver. Special collector items, such as certain proof sets, may also contain silver versions of contemporary coins.

which half dollar coins are silver

Ah, the great half dollar treasure hunt! You're wondering if that coin you found is just lunch money or a little silver windfall. Let's break down the metallic mystery of the U.S. half dollar. The golden rule, or rather the silver rule, is that any half dollar minted in 1964 or earlier is the real McCoy, packing a hefty 90% silver content. This glamorous group includes the Barber, Walking Liberty, Franklin, and the very first 1964 Kennedy half dollars. If the date on your coin is 1964 or before, congratulations, you've struck 90% silver. Then came the awkward transitional phase. From 1965 to 1970, the U.S. Mint wasn't quite ready to quit silver cold turkey. The Kennedy half dollars produced in these years have a 40% silver content. Think of them as "silver-lite" – not the full-flavored classic, but still valuable for their silver. After 1970, the silver party for circulating coins was officially over. Any regular half dollar you get in your change with a date of 1971 or later is made of a copper-nickel blend and contains precisely zero silver. It's worth exactly 50 cents, so feel free to spend it on gumballs without regret. However, there's a little secret for collectors. The U.S. Mint started producing special silver proof sets for collectors again in 1992, containing Kennedy halves made of 90% silver. So, while you won't find these in circulation, the Mint never fully gave up on making shiny silver half dollars for its biggest fans.

what is the value of an eisenhower 1971 silver dollar

While the provided context does not offer specific price details, I can certainly guide you on what determines the value of your 1971 Eisenhower dollar. Unlocking its true worth is an exciting process, and it all starts with identifying which version of the coin you possess. The most critical factor for a 1971 Eisenhower dollar is its metal composition. You've asked specifically about the "silver" dollar, which is the key to finding real value. To confirm you have a silver version, look for an "S" mint mark on the front of the coin, just below the portrait of President Eisenhower. If you see that "S," your coin was struck at the San Francisco Mint and is composed of 40% silver. These were never intended for circulation and were created specifically for collectors. The value of these 40% silver "S" mint coins is based primarily on their silver content, often called their melt value, which fluctuates with the daily market price of silver. Beyond that, they carry a numismatic premium that depends on their condition. The uncirculated versions, which originally came in blue envelopes, and the mirror-like proof versions, sold in brown boxes, are the most sought-after and will command a higher price than the base metal value. It's crucial not to confuse the silver version with the common Eisenhower dollars made for circulation. Those coins were minted in Philadelphia (no mint mark) or Denver ("D" mint mark) and contain no silver. They are made of a copper-nickel alloy. Unless one is in pristine, professionally graded uncirculated condition, these non-silver dollars are typically worth only their face value of one dollar. So, take a close look at your coin—that little "S" is the most important detail in discovering its true value.

what makes a 1886 silver dollar rare

The rarity of an 1886 silver dollar is primarily determined by two key factors: its mint of origin and its physical condition. While millions of these coins were produced, most are not considered rare. The United States Mint produced the 1886 Morgan dollar at three different locations. The Philadelphia Mint produced nearly 20 million coins (which have no mint mark), and the New Orleans Mint struck over 10 million (identified by an 'O' mint mark). Due to these high production numbers, the 1886 and 1886-O silver dollars are extremely common in most grades and are generally not rare. The key to rarity for this year lies with the San Francisco Mint. The 1886-S Morgan dollar had a significantly lower mintage of only 750,000, making it the rarest of the three varieties and the "key date" for collectors. Beyond the mint mark, the coin's condition is a crucial factor for all three versions. A vast majority of Morgan dollars entered circulation and show signs of wear. Therefore, any 1886 silver dollar, regardless of its mint, that has been preserved in a high-grade, uncirculated state (such as MS-65 or higher) is considered rare and is highly sought after by numismatists. Specific minting errors or varieties can also contribute to a particular coin's rarity.

what is the value of a canadian silver dollar today

Hello there! That's a great question. The value of a Canadian silver dollar today isn't a single, fixed price because it depends on two main things: its silver content and its value as a collector's item. First, there's the "melt value," which is based on the amount of silver in the coin and the current market price for silver. Canadian silver dollars made for circulation between 1935 and 1967 contain 80% silver, so they will always be worth at least their weight in silver. This gives them a solid base value that fluctuates daily with the market. However, the bigger factor for many of these coins is their numismatic, or collector, value. Based on the information from Greysheet, the value varies significantly by the year the coin was issued. Some years are much rarer than others and are highly sought after by collectors. For example, a 1948 silver dollar is a famous rarity and is worth far more than a more common date from the 1960s. The coin's condition is also critical. A coin in crisp, almost uncirculated (AU) condition, like those mentioned by BullionMax, will fetch a much higher price than a coin that is heavily worn from being in circulation. In short, to determine the value of a specific Canadian silver dollar, you need to identify its year and assess its condition. A common-date coin in circulated condition might be worth around its silver melt value, while a rare date in pristine condition could be worth a great deal more.

who is on the morgan dollar

The figure depicted on the obverse, or "heads" side, of the Morgan dollar is a profile portrait of Lady Liberty. This particular representation is notable because, unlike many earlier designs that were based on classical or mythological figures, it was modeled after a real American woman. The coin's designer, George T. Morgan, used Anna Willess Williams, a schoolteacher from Philadelphia, as the model for Liberty's portrait. The choice to feature a contemporary American woman for the iconic figure was a distinct departure from previous coinage. The reverse side of the coin features an American bald eagle with its wings outstretched, a classic symbol of the nation.
