Why Mints Matter
Why is this discovery so important? Knowing a coin's mint of origin allows you to understand just how scarce it really is. For example, the 1885 Morgan Silver Dollar was struck at several branches of the U.S. Mint. From the Philadelphia Mint, a coin in Brilliant Uncirculated (BU) condition can cost you around $70. But add in the coveted "CC" mint mark of the Carson City Mint, and an 1885 Morgan in the same exact condition is suddenly worth nearly $900!
This is not an isolated example. You can also look at the 1995-W Silver Eagle Proof, the first Silver Eagle to bear the "W" mint mark of the West Point Mint. While a 1995 Silver Eagle Proof struck at the Philadelphia Mint is listed by NGC as being worth $375 in flawless condition, a perfect 1995-W, a coin that is far more scarce, is worth over $18,000!
