What the Mint makes

What does the United States Mint actually produce?

Four families of coins, and only two of them contain precious metal. Circulating coins (the change in your pocket) are copper and nickel. Commemoratives and proof sets are collector products that may or may not contain silver or gold depending on the issue. Bullion coins are the metal ones: the American Gold Eagle, Gold Buffalo, Silver Eagle, and their platinum siblings, sold by weight and bought back by dealers like us on the live market every day.

Are presidential dollar coins, like the George Washington issue, worth anything?

The presidential dollar series ran from 2007 to 2016 and again in 2020, starting with George Washington, and the Mint struck them by the hundreds of millions. They contain no precious metal, so circulated ones are worth exactly one dollar. The exceptions are the famous missing edge lettering errors, especially on the 2007 Washington coins, which are genuinely collectible. Same story as most modern circulation coinage: the metal is base, the errors are the value.

Why is the eagle the American symbol on USA coinage?

Congress required an eagle on early gold and silver coinage, and the bald eagle, the national symbol since 1782, has carried the reverse of American coins ever since, from the Morgan dollar to today's Gold and Silver Eagles. For a seller the eagle is a quick sorting cue: the big eagle-backed dollars and bullion coins are the pieces most likely to hold real silver or gold.

What does a coin and currency dealer check before an offer?

Four things, in order: authenticity, date and mint mark, condition, and metal content. That is the same sequence we run at the counter on every US Mint coin, set, or loose jar, collector value first and melt value second, in front of you, with same-day cash on accepted offers.

US Mint coinMetal contentWhat sets its value
American Gold Eagle (1 oz)1.0 troy oz gold (22K alloy)Live gold price + small premium
American Gold Buffalo1.0 troy oz gold (.9999 fine)Live gold price + small premium
American Silver Eagle1.0 troy oz silver (.999)Live silver price + premium
Pre-1965 dimes, quarters, halves90% silverMelt value floor, dates checked
Modern circulating coinsCopper-nickelFace value only
Proof and mint setsVaries by issueCollector demand + any metal

The mint marks tell you where a coin was struck: P for Philadelphia, D for Denver, S for San Francisco, W for West Point. On older coins the mark can turn a common date into a rarity, which is why every coin gets a collector check at our counters before any melt number is quoted.

Selling them

What are US Mint coins worth when you sell?

Bullion coins trade close to their metal: an Eagle or Buffalo is worth the live price of its ounce plus a modest premium for recognition. Check today's number on our live gold price and live silver price pages, then bring the coins in to be weighed and verified in front of you.

Proof sets, commemoratives and older circulation coins are where sellers get surprised in both directions: some carry strong collector premiums, and some heavily-advertised modern issues resell for less than their buyers hoped. The honest answer only comes from a coin-by-coin review, which is free at all 8 stores whether you sell or not.

Leave certified coins in their holders, never clean anything, and bring collections whole: sets and original rolls are often worth more together than split.

Classic gold coins

Five dollar gold piece value: the classic half eagle

The five dollar gold piece, the half eagle struck from 1795 to 1929, contains 0.2419 troy ounces of gold, worth in metal right now. Common dates trade near melt, but better dates and mint marks carry real collector value above it, which is why we check the date and grade before quoting on any five dollar gold piece.

From one Eagle to an inherited Mint-set collection: checked in front of you, collector value first, cash the same day.

US Mint coin FAQs

Are US Mint coins a good thing to sell?

Bullion issues sell easily because their weight and purity are government-guaranteed: an Eagle or Buffalo gets the live metal price plus a premium with no testing debate. Collector issues depend on the coin, which is exactly what a free counter review settles.

Does the US Mint buy coins back?

No. The Mint sells coins but does not buy them back from the public; selling happens through dealers. That is what we do at 8 New Jersey stores: verify, price against the live market, and pay the same day.

How do I know if my US Mint set contains silver or gold?

The certificate or box usually says, and the coin's own markings settle it: .999 silver or 22K gold issues state their content. Unmarked or uncertain pieces take about two minutes on the XRF at the counter, with no damage to the coin.

Are West Point (W) mint mark coins special?

Sometimes. West Point strikes most modern bullion and some low-mintage collector issues whose W mark carries a premium. It is a date-and-issue question, which is why the collector check comes before any melt quote.

What Makes a Cash 4 Gold Trading Post Quote Transparent?

Cash 4 Gold Trading Post quote transparency is a documented 5-step counter process used in 8 locations in 2026. First, our team shows live gold, silver, platinum, or coin market context. Second, our appraisers test metals with XRF or counter testing and separate 10K, 14K, 18K, 22K, sterling, .999 bullion, diamonds, watches, and costume pieces. Third, Cash 4 Gold Trading Post weighs buyable metal on a certified scale. Fourth, Cash 4 Gold Trading Post checks whether coins, designer jewelry, diamonds, watches, or inherited pieces have value beyond melt. Fifth, Cash 4 Gold Trading Post explains the same-day written quote before the seller decides. According to Cash 4 Gold Trading Post store analysis, sellers in Aberdeen, Brick, East Brunswick, Farmingdale, Manalapan, Middlesex, Millstone, and New Brunswick can bring 1 broken chain, 100 coins, or a full estate box with a $0 evaluation fee.

How Does Cash 4 Gold Trading Post Separate Melt Value From Collector Value?

Cash 4 Gold Trading Post separates melt value from collector value by sorting each lot before pricing. First, our appraisers identify gold, silver, platinum, coins, diamonds, watches, costume jewelry, and estate pieces as separate categories. Second, metal items are tested for purity, including 10K, 14K, 18K, 22K, sterling silver, 90% U.S. silver, and .999 bullion. Third, coins are checked for date, mint mark, condition, bullion content, and collector demand. Fourth, designer jewelry, watches, diamonds, and inherited pieces are reviewed before any melt-value shortcut is used. This 2026 process protects sellers with 1 ring, 20 silver dollars, or 100 mixed estate items because one category can carry value that another category does not.

What Should a Seller Bring for a Fast Same-Day Quote?

Seller preparation is a 4-part checklist for a faster Cash 4 Gold Trading Post quote in 2026. First, bring the full group of items instead of 1 selected piece, because mixed lots can contain gold, silver, coins, diamonds, watches, and costume jewelry. Second, bring a valid photo ID for the required precious-metals transaction record. Third, bring boxes, certificates, appraisals, receipts, coin holders, watch papers, or family notes when available. Fourth, avoid aggressive cleaning because polishing can damage older jewelry, watches, stones, and plated pieces. Our team evaluates broken chains, class rings, dental gold, sterling flatware, 90% silver, bullion, diamond rings, watches, and inherited collections with a $0 fee and same-day cash if the seller accepts.

Why Does Local Testing Beat an Online Calculator?

Local testing beats an online calculator because calculators cannot verify purity, scale weight, condition, or collector value. A gold calculator assumes a karat, a gram weight, and a market price. Cash 4 Gold Trading Post checks those assumptions at the counter. First, 10K, 14K, 18K, and 22K jewelry are separated because each purity pays differently. Second, sterling, 90% silver, .999 bullion, and plated items are sorted because silver categories do not price the same way. Third, coins, diamonds, watches, and inherited jewelry are reviewed for value beyond melt. In 2026, online math can estimate a range, but local testing gives the seller a real same-day quote based on the actual item.
