Understanding Proof Coins: Ultra Cameo, DCAM, Burnished, and Reverse Proofs

Nov 6

When browsing through coins—especially collectible or graded ones—you might notice terms like Ultra Cameo, DCAM, Burnished, or Reverse Proof. These designations describe how a coin was struck and finished, giving collectors insight into its beauty, rarity, and value. At Houston TX Coins, we often get questions about what these terms mean and how they affect a coin’s desirability. Let’s break it down.

What Is a Proof Coin?

A proof coin isn’t just a shiny coin—it’s a specially made version of a coin struck using polished dies and carefully prepared planchets (blanks). Proofs are made for collectors, not for circulation. They’re known for their mirror-like fields, frosted details, and exceptional sharpness.

Now let’s look at the different finishes and designations you’ll encounter:

1. Cameo and Deep Cameo (DCAM) or Ultra Cameo (UCAM)

These terms refer to the contrast between the coin’s background (the “field”) and the raised designs (the “devices”).

Cameo (CAM): The devices have a light frosted finish that contrasts nicely against a mirrored background.
Deep Cameo (DCAM) or Ultra Cameo (UCAM): These coins show an even stronger contrast—the frosting is heavy and the background is deeply reflective, almost glass-like.

Fun fact: The first few proof coins struck from a fresh die usually have the strongest cameo contrast, making them especially valuable to collectors.

2. Burnished Coins

Burnished coins are not proofs, but they often get grouped with them because of their distinctive finish.

A burnished coin starts as a regular uncirculated coin, but before minting, the blanks are tumbled with tiny beads to create a smooth, matte-like surface. They’re then struck once and often bear a small mint mark, like the “W” for West Point.

This gives them a soft, satin finish—less reflective than a proof, but more refined than a typical uncirculated coin. The U.S. Mint began producing burnished silver eagles in 2006, and collectors love them for their subtle elegance.

3. Reverse Proof Coins

A reverse proof flips the typical proof appearance: the background is frosted, while the raised designs are mirror-polished.

This striking contrast gives the coin a bold, dramatic look that stands out in any collection. Reverse proofs are modern creations, often released as limited-edition collectibles. They’ve become especially popular in American Silver Eagle and commemorative coin series.

Why These Finishes Matter to Collectors

Proof designations aren’t just about looks—they also signal craftsmanship, scarcity, and value.

Ultra Cameos and Reverse Proofs are prized for their dramatic beauty.
Burnished coins appeal to collectors who appreciate subtle, high-quality finishes.
Each type showcases the artistry and technical skill of the U.S. Mint.

When selling or appraising your coins, these finishes can make a significant difference in what your collection is worth.
