The 2006-S Sacagawea Dollar is worth anywhere from $5 in standard proof condition to over $1,200 for high-grade specimens. While these coins often look like solid gold, they are actually made of a copper core clad in manganese brass, making them a unique piece of modern American history.

Condition/Grade	Estimated Market Value
PR 65 (Deep Cameo)	$5.00 – $8.00
PR 69 (Deep Cameo)	$15.00 – $25.00
PR 70 (Deep Cameo)	$65.00 – $150.00+

Understanding the 2006-S Sacagawea Dollar Rarity

If you just found a shiny “gold” dollar in your change or an old jar, you might be holding a 2006 Sacagawea dollar. It is important to know that by 2006, the U.usercontent.com Mint was no longer producing these coins for general circulation. Instead, they were minted specifically for collectors in rolls, bags, and proof sets. This makes them significantly harder to find in your pocket change than the common 2000-P versions. To quickly identify what you have, many hobbyists use a top coin identifier app to screen their finds before visiting a dealer.

The “S” mint mark on your 2006 coin indicates it was produced at the San Francisco Mint. Unlike the “P” (Philadelphia) or “D” (Denver) versions, the “S” coins were exclusively issued as “Proof” coins. Proofs are struck using special polished dies and planchets, resulting in a mirror-like background and frosted details.

Because these were sold directly to collectors, most 2006-S coins are still in excellent condition. However, if you find one that has been “impaired” (meaning it was spent and spent until it lost its shine), its value drops significantly. Using the CoinKnow app can help you determine if your coin’s luster is factory-original or simply a cleaned surface.

The Visual Appeal of the Proof Sacagawea Dollar

What sets the 2006-S apart is the “Deep Cameo” finish. On a high-quality proof, the portrait of Sacagawea and her infant son, Jean Baptiste Charbonneau, appears almost white and snowy against a dark, reflective mirror field. This contrast is highly prized by collectors. The reverse features an eagle in flight, also rendered in high relief.

When evaluating these coins, collectors look for any tiny scratches, known as “hairlines,” which can occur even if the coin was only handled once with bare fingers. The oils from your skin can actually damage the delicate manganese-brass finish over time. If you think you have a perfect specimen, checking the 2006 Sacagawea dollar value online is the first step toward professional grading.

If you are unsure whether your coin is a proof or just a very shiny business strike, look for the mint mark near the date. Only the San Francisco mint produced the Proof versions in 2006. If you find a “P” mint mark, you should check the current market data for 2006-P Sacagawea dollars to see how they compare in value.

Mint Mark	Mintage Type	Total Reported Mintage
2006-P	Business/NIFC	4,900,000
2006-D	Business/NIFC	2,800,000
2006-S	Proof Only	3,054,436

Grading and How It Affects Your Coin’s Worth

In the world of coin collecting, “Grade” is everything. Coins are graded on a scale from 1 to 70. For a 2006-S Proof Sacagawea Dollar, anything below a PR 67 is considered “common.” Most collectors only pay premium prices for coins that achieve a perfect PR 70 grade from reputable services like PCGS or NGC.

A PR 70 coin is flawless under 5x magnification. Because the CoinKnow app allows you to zoom in on high-resolution photos of your coins, you can often spot minor imperfections before deciding to pay for professional grading. If your coin has even a single microscopic scratch on Sacagawea’s cheek, it will not reach that coveted $100+ price point.

Interestingly, many of these coins were part of the “Silver Proof Set,” but the Sacagawea dollar itself was never minted in silver. It remains a base-metal coin, which means its value is derived entirely from its condition and its demand among collectors who are trying to complete “registry sets.”

Are There Any 2006-S Sacagawea Errors?

While error coins are the holy grail for many treasure hunters, the 2006-S Sacagawea Dollar is known for having very high quality control. Proof coins are inspected individually by mint employees, so errors like “double dies” or “off-center strikes” are incredibly rare and highly valuable.

One thing to look for is “Toning.” Due to the manganese in the alloy, these coins can sometimes develop a golden-orange, purple, or even bluish tint over time if they are exposed to certain environmental conditions. While “spotting” (white milk spots) reduces the value, attractive “rainbow toning” can actually increase the price of a 2006-S dollar significantly among specialist buyers.

Before you get too excited about a potential error, use CoinKnow to browse known error types. Most “weird-looking” coins found in circulation are actually just damaged or chemically altered after they left the mint. True proof errors are often worth hundreds, if not thousands, of dollars because they shouldn’t exist.

Market Pricing and Where to Sell Your Coin

When you are ready to sell, it is important to realize that “Book Value” is different from “Cash in Hand.” If you take a 2006-S Sacagawea Dollar to a local coin shop, they likely already have many in stock. They might offer you $2 to $4 for a typical proof so they can resell it for $6.

To get the best price, selling through online marketplaces or specialized coin auctions is usually better, especially if your coin is professionally graded. High-grade PR 70 specimens are frequently traded on eBay, where collectors are willing to bid top dollar to fill a specific hole in their collection.

Auction Sale Date	Grade	Price Realized
January 2021	PCGS PR70DCAM	$156.00
August 2022	NGC PR70 Ultra Cameo	$110.00
March 2023	PR 69 (Raw)	$12.50

Conclusion: Is It Worth Keeping?

While the 2006-S Sacagawea Dollar isn’t going to fund your retirement, it is a beautiful piece of American minting excellence. Finding one in circulation is a lucky strike, given that they were never intended to be spent. If you find one in a protective plastic case, keep it there! Exposure to air and touch is the fastest way to turn a $20 coin into a $1 coin.

Whether you are a serious numismatist or just a curious homeowner, these coins serve as a reminder of the transition period in US coinage. Their limited mintage compared to the billions of pennies and quarters produced annually ensures they will always have some level of collector interest.

FAQ

Q: Is the 2006 Sacagawea Dollar made of gold?

A: No. Despite its golden color, it contains zero gold. It is made of a core of pure copper with an outer layer of 77% copper, 12% zinc, 7% manganese, and 4% nickel. This mixture gives it that distinctive golden hue.

Q: How can I tell if my 2006 dollar is a “Proof” coin?

A: Look for the mint mark “S” on the obverse (heads) side. Also, observe the finish: if the background is shiny like a mirror and the portrait is frosted/matte, it is a proof coin. “P” and “D” mint marks are standard business strikes.

Q: Where is the mint mark on a 2006 Sacagawea Dollar?

A: The mint mark is located on the front of the coin, just below the date (2006) on the right-hand side, near Sacagawea’s shoulder.

Q: Why is my 2006 Sacagawea Dollar turning brown or black?

A: This is due to oxidation of the manganese in the alloy. Manganese reacts easily with moisture and oils, causing the coin to “tarnish” or develop an oily-looking patina. This is very common for coins that have been handled or stored improperly.
