Start Spotting Silver Eagle Errors
New to coin collecting? Don’t worry – we’ve all been there. I’ll never forget my first time holding a magnifying glass over a Silver Eagle, heart pounding as I tried to figure out if that odd mark was a mint error or just a smudge. Let’s capture that excitement as we walk through strike-through errors together.
Silver Eagle Basics Every Collector Should Know
Before hunting for errors, let’s cover what makes Silver Eagles stand out:
Why Collectors Love These Coins
- Debuted in 1986 as America’s official silver bullion coin
- Each contains a full ounce of .999 pure silver
- Features the stunning Walking Liberty design
- Struck at three U.S. Mint facilities
How Perfect Silver Eagles Are Made
Knowing the normal minting process helps you spot what’s wrong. Each coin gets pressed between two dies with massive force – about the weight of a small elephant! Here’s how it works:
- Preparing blank coins (planchets)
- Setting up the stamping dies
- Striking the design onto silver
- Checking for quality
Mint Errors Explained Simply
When something goes wrong at the mint, we get error coins. These usually fall into three groups:
Error Types Made Easy
- Blank Problems: Flaws in the silver disc before stamping
- Die Issues: Mistakes in the stamping tools
- Striking Slip-ups: Errors during the pressing
Cracking the Code on Strike-Through Errors
This is where things get interesting. Strike-through errors happen when something gets in the way during stamping. Let me show you what to look for:
What a Strike-Through Really Looks Like
These errors leave two types of marks:
- Imprinted: Where the object pressed into the coin
- Blank Spots: Where the object blocked the design
Behind the Scenes at the Mint
From talking with mint staff, here’s what often causes these errors:
“Those plastic bits you sometimes see? They’re usually from protective die wrapping that didn’t get fully removed before striking.”
Other common troublemakers:
- Lint from cleaning rags
- Tiny metal flakes
- Dust particles in the air

Error Coin Myths You Might Be Surprised By
After years of collecting, here are the biggest misunderstandings I’ve seen:
“Every Error Makes a Coin Valuable”
Reality: Only noticeable, interesting errors increase value. Tiny marks might actually lower it.
“A Quick Clean Won’t Hurt”
Reality: Cleaning can ruin both value and error evidence. Don’t do it!
“Errors Are Nearly Impossible to Find”
Reality: With billions of coins made, plenty escape quality checks. They’re uncommon but findable!
What’s Your Error Coin Worth?
When I found my first valuable error, I learned these three valuation rules:
Error Visibility Levels
- Small: Needs magnification (slight value boost)
- Clear: Visible without tools (good premium)
- Obvious: Jumps out at you (big value increase)
Getting Your Coin Certified
For potentially valuable finds, always use grading services like PCGS or NGC. They’ll:
- Confirm it’s genuine
- Seal it in protective casing
- Give it market credibility
