Hey friend,
So you've been out there looking. Maybe you hit a flea market last weekend. Maybe you dug through a jar of old coins at a garage sale. Maybe you finally pulled out that box of coins you inherited and started going through it properly.
And now you're sitting there holding a coin, squinting at it, thinking:
"Is this worth anything? Or am I getting excited over nothing?"
I've been there more times than I can count. And I'll be honest — in the beginning I got it wrong a lot. I got excited about coins that turned out to be worth face value. And I completely overlooked coins that turned out to be worth real money.
So today I'm giving you the exact 60-second process I use to decide whether a coin is worth keeping, researching further, or tossing back in the junk bin.
Let's get into it.
🪙 ONE COIN TO KNOW THIS WEEK
The Walking Liberty Half Dollar
If the Mercury Dime is one of the most beautiful small coins ever made, the Walking Liberty Half Dollar is its big sister.
Minted from 1916 to 1947, every single one is 90% silver. But beyond the silver content, collectors genuinely love this coin — the design by Adolph Weinman is considered a masterpiece. In fact, the U.S. Mint liked it so much they used a version of it for the American Silver Eagle, which is still minted today.
What to look for:
Dates from 1916 to 1947
Lady Liberty walking toward the sunrise on the front
An eagle on the reverse
Key dates to watch: 1916, 1917-D (obverse), and 1921 — these are worth significantly more than common dates
Even heavily worn common dates are worth $10–$15 in silver content alone
When you find one of these in a junk bin, it feels like finding a small piece of art. Keep every single one you come across.
🔎 THIS WEEK'S MAIN TOPIC
How to Tell in 60 Seconds If a Coin Is Worth Keeping
Here's the process. Simple, fast, and it works.
Second 1–10: Check the Date
This is always your first move.
Older doesn't automatically mean valuable — but date is one of the three things that determines almost every coin's worth. Get in the habit of checking it immediately.
Anything pre-1965 in silver denominations (dimes, quarters, half dollars) gets set aside automatically. That's your silver pile, and it has value regardless of anything else.
Anything from the 1800s or early 1900s in any denomination gets a closer look. Age isn't everything, but it's a signal worth paying attention to.
Second 10–20: Check the Mint Mark
The mint mark is a small letter stamped on the coin — usually on the front, sometimes on the back depending on the coin type.
No letter = Philadelphia Mint
D = Denver Mint
S = San Francisco Mint
O = New Orleans Mint (older coins only)
CC = Carson City Mint (older coins only — and often very valuable)
Why does this matter? Because the same coin from different mints can have wildly different values. A 1909 Lincoln Cent from Philadelphia is worth a few dollars. A 1909-S VDB from San Francisco — like the one Marie found in that thrift store folder last week — is worth several hundred.
Same year. Completely different coin.
Second 20–35: Check the Condition
Condition affects value more than most beginners expect.
You don't need to know the full grading scale right now. Just think in three buckets:
Heavily worn — details are flat, hard to read. Still worth keeping if it's silver or a key date, but value is lower.
Moderately worn — you can see most of the design clearly. Good.
Lightly worn or uncirculated — sharp details, possibly some original shine. This is where values can jump significantly.
One important rule here: don't confuse dirty with worn. A coin can be dark and ugly and still have sharp detail underneath. Never clean it to find out — just look carefully in good light.
Second 35–50: Check for Errors
This is the fun part.
Coin errors happen when something goes wrong at the mint — a die breaks, a coin gets struck twice, something gets misaligned. These mistakes, which the mint tried to destroy, sometimes slip through into circulation. And collectors pay serious premiums for them.
What to look for:
Doubled die — lettering or design elements that look slightly doubled or blurry in a specific way (not from wear)
Off-center strike — the design isn't centered on the coin
Wrong planchet — a coin struck on the wrong metal blank (these are rare but wild when you find one)
You won't find errors every day. But it takes five seconds to glance and check — and the day you find one, you'll be very glad you did.
Second 50–60: Make the Call
By now you have enough information to decide:
Keep and research — it's silver, it's old, it has a key date or mint mark, or something looks unusual about it.
Keep in the maybe pile — you're not sure yet. That's fine. Set it aside and look it up later.
Move on — it's a common modern coin with no silver content, no errors, and nothing unusual. Back it goes.
That's the whole process. Sixty seconds. The more you do it, the faster and more instinctive it becomes.
⚡ QUICK TIP OF THE WEEK
Good lighting changes everything.
I can't tell you how many times I've picked up a coin in dim light, thought it was nothing, and then held it up to a window and realized it was something.
Natural light from a window is ideal. If you're sorting coins at night, a bright LED desk lamp pointed at an angle across the coin (not straight down) will show you details and luster you'd completely miss otherwise.
Carry a small flashlight if you're buying at flea markets or estate sales. It makes a real difference when you're digging through a dim junk bin.
📈 WHAT'S HAPPENING IN THE MARKET
Something interesting is happening with Walking Liberty Half Dollars right now.
Demand from newer collectors has been quietly pushing prices up on mid-grade examples — coins that aren't in perfect condition but still show good detail. The entry-level price for a decent Walking Liberty has crept up noticeably over the past year.
What this means for you: if you find them in junk bins priced at melt value, you're getting a quiet deal. And if you already have some sitting in a box somewhere, they may be worth a little more than you think.
Worth checking current sold listings on eBay if you have any.
🔍 AUGUST'S FIND OF THE WEEK
I want to share something a little different this week — a miss, not a win.
A few months ago I was at an estate sale and found a 1955 Lincoln Cent. I got excited — 1955 is a famous date because of the 1955 Doubled Die error, one of the most well-known error coins in American numismatics.
I didn't have my loupe with me. I bought it for $2 assuming it might be the error.
It wasn't. It was a perfectly normal 1955 cent worth about 5 cents.
The lesson isn't that I wasted $2 — that's nothing. The lesson is: always bring your loupe. A $10 magnifier would have saved me the false excitement and the $2. More importantly, it would have confirmed a genuine doubled die if I'd actually found one.
Tools matter. Even simple ones.
BEFORE YOU GO
Your one thing to do this week:
Grab five random coins — from your pocket, a jar, wherever — and run them through the 60-second process. Date, mint mark, condition, errors. Just practice.
You'll probably find nothing exciting. That's fine. The point is building the habit so that when you do sit down with a real inherited collection or a flea market find, your eye is already trained.
Practice on boring coins so you're ready for the interesting ones.
See you next week.
— August
