Modern coin labels can include several terms that are confusing at first: burnished, MS70, Advance Releases, First Day of Issue and more. Each tells you something about how a coin was made, its condition or when it was released. Here is what they mean.
What Is a Burnished Coin?
Burnished describes how a coin is made, not its condition. For burnished coins, the U.S. Mint uses specially prepared blanks that are tumbled and polished before striking, then fed into the press one at a time. The result is a soft, satin-like matte finish that many collectors love.
- Burnished American Eagles were first issued in 2006.
- They carry a mint mark — usually the “W” of the West Point Mint.
- They are typically produced in smaller quantities than bullion coins.
- The U.S. Mint often sells them as “uncirculated” coins, and some grading services label them as Specimen (SP) strikes.
The Grade: Why MS70 and PF70 Matter
Coins are graded on the Sheldon scale from 1 to 70. A grade of 70 means the coin shows no post-production imperfections under 5x magnification. Because modern coins are generally well preserved, collectors of modern issues especially prize coins certified in perfect MS70 (Mint State) or PF70 (Proof) condition.
Certified Population
Grading services record how many coins they have certified for each date, mint mark, grade and special designation. This certified population helps collectors understand how scarce a particular combination is. Low original mintage and a low certified population often go hand in hand with higher collector demand.
Early Release Designations
Grading services offer special labels for coins documented as coming from the earliest releases of a new issue. The exact names and rules depend on the service, but common examples include:
- First Day of Issue / First Day of Release: coins documented as released, shipped or acquired on the first day of sale.
- Early Releases / First Strike: coins received by the grading service within a set period after release, often 30 days.
- Advance Releases: coins documented as coming from the very first shipments, before general public availability.
Because these designations cover only a small portion of each mintage, they generally have lower certified populations, which many collectors find appealing.
Signatures
A coin can also carry a hand-signed label from someone closely connected to the coin, such as its designer or a former mint director. A meaningful signature, combined with a top grade and an early release designation, creates some of the most exclusive certified coins available.
The Bottom Line
When reading a modern coin label, look at three things: how the coin was made (bullion, burnished or proof), its grade, and any special designation or signature. Together they explain why two coins of the same year can have very different collector values.
