What Are Mint Marks? A Quick Guide for Coin Collectors in The Woodlands

If you’ve ever looked closely at a coin and noticed a small letter near the date—like “D,” “S,” or “P”—you’ve spotted something important: a mint mark. For coin collectors, these tiny letters can make a huge difference in value. At Woodlands Gold and Coin, we regularly help customers identify rare mint marks when selling coins in The Woodlands.
So, what exactly are mint marks? And why should you care about them when selling silver, gold, or collectible coins? Let’s break it down.

What Is a Mint Mark?

​A mint mark is a small letter stamped on a coin that indicates which U.S. Mint facility produced it. These letters help collectors and dealers identify a coin’s origin and, in many cases, its rarity. Coins with certain mint marks may be far more valuable than the same coin without one.

​U.S. Mint Mark Codes

Here are the most common U.S Mint Marks you'll see: 

• Philadelphia (P) 
• Denver (D) 
• San Francisco (S)
• Carson City (CC) 
• New Orleans (O) 
• West Point (W) 

For example, a Morgan Silver Dollar with a "CC" mint mark from Carson City is usually much rarer and more desirable than one with a Philadelphia "P" mark - or no mint mark at all. 

Were to Find the Mint Mark 

On most U.S. coins, the mint mark appears:

• Near the date (on the obverse/front)
  
• On the reverse (back) for some older coins
  
• On coins like the Morgan Dollar, just below the eagle on the reverse
  

If you can’t find a mint mark, it’s often because the coin was made in Philadelphia, which didn’t always use a mint mark (especially before 1980).

Why Mint Marks Matter When Selling Coins in The Woodlands

When you're selling coins in The Woodlands, that little letter can change everything. For example:

• A 1921 Morgan Dollar from Philadelphia might sell for $17.
• A 1921 Morgan Dollar from San Francisco (S) could fetch more—especially in better condition.
• A Carson City (CC) Morgan could bring hundreds of dollars, even if lightly worn.

That’s why working with an experienced coin buyer in The Woodlands like Woodlands Gold and Coin is important. We know what to look for, and we’ll make sure you don’t accidentally sell a rare mint mark for too little.
