Common Coin Myths & Mistakes — Don’t Get Fooled

The world of coin collecting is full of excitement, surprises, and unfortunately… misinformation.
Between old family stories, Google search results, and viral social media videos, it’s easy to believe something about coins that simply isn’t true.
And when you’re trying to sell a collection — or figure out what you actually have — these myths can cost you real money.
As a professional appraiser serving Houston and surrounding areas, Sean Summerlin sees the same myths and mistakes over and over again.
Here’s a guide to help you avoid the most common ones.

Myth #1: “All old coins are automatically valuable.”

Not true.
Age doesn’t guarantee value.
A 100-year-old coin might be worth a dollar — while a coin from the 1960s might be worth hundreds.
Value depends on:

• Condition
  
• Rarity
  
• Mint mark
  
• Silver or gold content
  
• Collector demand
  

Some old coins are valuable. Many aren’t.
Only an expert can tell the difference.

Myth #2: “Shiny coins are worth more.”

In the coin world, shiny does not equal valuable.
Most shiny coins have been:

• Polished
  
• Cleaned
  
• Scrubbed
  
• Damaged
  

Cleaning almost always lowers a coin’s value because it removes natural toning and original mint luster.
If you want your coins evaluated properly:
👉 Never clean them. Bring them in as-is.

Myth #3: “Modern State Quarters are collectible and rare.”

State quarters were exciting when they came out — but they were printed in the billions. That means:

• They are not rare
  
• They are not valuable
  
• They are worth face value unless there’s an error
  

If you have a bucket of state quarters, chances are… it’s worth $0.25 each.

Myth #4: “Every silver-looking coin is real silver.”

Many people find coins that look silver and assume they’re valuable.
But appearance can be misleading.
Real silver coins (U.S.) are mostly:

• 90% silver if dated 1964 or earlier
  
• 40% silver for some 1965–1970 half dollars
  
• Clearly labeled bullion (Silver Eagles, proofs, commemoratives)
  

Modern dimes, quarters, and nickels are copper-nickel, even if they look silver.
If you're unsure, Sean Summerlin can quickly test and identify the metal for you.

Myth #5: “I saw this coin on Google for $10,000 — mine must be too!”

Online search results can be misleading.
Many people mistake:

• Listing prices for actual sold prices
  
• High-grade examples for circulated ones
  
• Rare dates for common ones
  

A coin on the internet listed for $10,000 may actually sell for $30 in real life.
Accurate value comes from real market knowledge — not Google images.

Myth #6: “If it’s in an old family envelope or holder, it must be special.”

People often bring in coins stored in envelopes marked:

• “RARE”
  
• “VALUABLE”
  
• “UNC.”
  
• “KEEP”
  

Unfortunately, these labels were often written by:

• Family members
  
• Hobbyists
  
• Banks
  
• Estate holders
  

…not professional graders.
The packaging doesn’t determine value — the coin itself does.

Myth #7: “I can grade my own coins at home.”

Grading is extremely technical.
Even experienced collectors disagree on grades.
Professional grading considers:

• Strike
  
• Luster
  
• Surface preservation
  
• Eye appeal
  
• Microscopic details
  

Getting a grade wrong by one level can change a coin’s value by:

• 50%
  
• 100%
  
• Sometimes thousands of dollars
  

Let a professional appraiser like Sean Summerlin evaluate your coins before you assume value.

Myth #8: “It’s better to spend or exchange old coins at a bank.”

Never, ever do this.
Banks will:

• Give you face value only
  
• Mix your coins with regular circulation
  
• Remove any chance of recovering collector value
  

Even a silver dime is worth significantly more than 10 cents.
When in doubt, have it checked.
