Someone Left Me a Coin Collection — Is It Worth Anything? (What to Do in the First 48 Hours)
Let me guess.
You weren't expecting this.
Maybe it was a box in the back of a closet. Maybe it came up at the end of an estate sale, or someone handed it to you and said "here, you should have this." And now you're sitting with a collection of coins you know nothing about, wondering if you're holding something meaningful — or just a lot of old change.
I want you to take a breath. Because that feeling of not knowing where to start? Completely normal. I've heard from so many people in exactly this situation, and the good news is this: you don't need to be a coin expert to figure out what you have. You just need to know what to do first.
That's what I'm going to walk you through today.
Before Anything Else — Please Don't Do This
I know the instinct. You want to sort through everything, clean it up, maybe look a few things up online. And most of that is fine.
But there's one thing I need you to hear before you touch a single coin:
Do not clean anything.
Not with water. Not with a cloth. Not with one of those coin cleaning kits you might find at a craft store. Not even a gentle wipe.
I know that sounds counterintuitive. A cleaner coin should be worth more, right? In almost every other context in life, clean and shiny means better. But in the coin world, it's the opposite. Cleaning a coin permanently damages the surface in ways that collectors and dealers can spot immediately — and it can turn a coin worth hundreds of dollars into one worth a fraction of that.
I've seen it happen. It's heartbreaking and completely avoidable.
So before we talk about value, before we talk about selling, before we do anything else: hands off, no cleaning. Just look.
Okay — So Is It Worth Anything?
Here's the honest answer: it might be. It might be worth quite a lot. Or it might be mostly face value with a few interesting pieces mixed in.
The truth is, I can't tell you without knowing what's in there — and neither can anyone else until you take a closer look. But what I can tell you is that inherited collections have a way of surprising people. The person who built this collection spent time and thought on it. That often means there's more there than meets the eye.
Let me show you what to look for.
Start Here: A Quick First Pass
You don't need to identify every coin right now. All you're doing in the first 48 hours is getting a basic sense of what you're working with.
Sort Into Rough Groups
Go through the collection and separate things into loose categories:
Coins in hard plastic cases (called slabs) with a label on them
Coins in albums or folders with individual slots
Loose coins mixed together
Anything that looks foreign or unusual
Paper money, if any ended up in the mix
This alone takes the chaos and turns it into something manageable. And it immediately tells you something useful — because those hard plastic slabs? Those are almost always the most valuable pieces in any collection. More on those in a minute.
Look for Any Paperwork
People who build coin collections often keep records. Price lists, receipts, old appraisals, handwritten notes. Check every folder, envelope, and box for anything like this. If you find documentation, hold onto it carefully — it can tell you a lot about what was collected intentionally and what it cost.
The Fastest Way to Spot Real Value
You don't need expert knowledge to find the potentially valuable coins. You just need to know a few basic signals.
Check the Dates on Dimes, Quarters, and Half Dollars
This is probably the single most useful thing a beginner can do in the first hour.
Any dime, quarter, or half dollar dated 1964 or earlier is made of 90% silver. That's not face value — that's real metal content with real market value, regardless of condition. Even a worn, ugly 1957 Roosevelt dime is worth several times its face value right now based on silver alone.
Kennedy half dollars from 1965 to 1970 are 40% silver — still worth more than 50 cents.
Flip through and pull anything that matches. You might be surprised how many you find.
Look at the Edges
Here's a quick trick. Look at the edge of a coin — the thin outer rim. If you see a copper-colored stripe running through it, the coin is clad — no silver. If the edge is solid and uniform in color with no stripe, it may be silver. It's not a perfect test, but it's a fast first filter.
I cover this in much more detail in my guide on how to tell if a coin is silver — worth reading after this one if you think you might have silver in the mix.

Pay Attention to the Professionally Graded Coins
Those hard plastic slabs I mentioned? If they have a label from PCGS or NGC — two of the most respected coin grading companies in the world — what's inside has been professionally authenticated and graded. These are almost certainly the most valuable coins in the collection.
Set them aside carefully. Don't remove the coins from the slabs under any circumstances. The grade on that label is part of the value.
Old Dates Are Worth a Second Look
Coins from the 1800s or very early 1900s tend to attract collector interest. That doesn't automatically mean high value — condition matters enormously — but age is a signal worth paying attention to. If you find anything with an 1800s date, set it aside for closer research.
How to Get a Rough Sense of Value Before Talking to Anyone
Here's something I feel strongly about: don't walk into a coin shop before you've done at least a little homework.
I'm not saying dealers are out to get you. Most are honest, knowledgeable people. But when you walk in knowing nothing and looking eager to unload everything quickly, you're at a disadvantage. You don't know what questions to ask. You might accept an offer that's far below what the coins are actually worth — and you'd have no way of knowing.
Thirty minutes of basic research can genuinely change the outcome.
Use eBay's Sold Listings
Search for a coin on eBay — let's say "1964 Roosevelt Dime" — then filter the results to show only sold listings. Not active listings. Sold listings show you what people actually paid in the real world, recently.
Match your coin as closely as you can: same year, same mint mark (a small letter on the coin, usually D, S, or no letter at all), similar condition. That gives you a real-world baseline, not a guess.
Use Free Online Price Guides
PCGS and NGC both offer free coin price guides on their websites. You can look up almost any U.S. coin by date and mint mark and get a sense of the value range. These aren't perfect — condition matters a lot and the guides can't see your coin — but they give you a starting point.
Search the Coin Name Plus "Value"
Simple Google searches like "1921 Morgan Dollar value" or "1909 Lincoln cent value" will pull up a lot of useful information quickly. Just be aware that you'll see a wide range of prices — condition is everything, and a coin in poor condition is worth far less than the top of the range you'll see listed.
Should You Get a Professional Appraisal?
If the collection looks substantial — multiple graded coins, old silver dollars, albums that appear carefully curated — it may be worth getting a professional appraisal before you do anything else.
A few things to know going in:
An appraisal is not the same as a sale offer. An appraiser tells you what the coins are worth. A dealer tells you what they'll pay — which is almost always less, because they need to resell and make a margin.
Look for appraisers who charge by the hour, not a percentage of the collection's value. A percentage-based appraiser has a financial incentive to overvalue.
The American Numismatic Association has a dealer directory that's a good place to start. Getting a second opinion on a large collection is never a bad idea.
What Are Your Options From Here?
Once you have a basic sense of what you're holding, you have a few directions you can go.
Sell everything — the most common choice, and a completely valid one. If coin collecting isn't your thing and you'd rather have the cash, that's fine. My guide on how to sell coins without getting ripped off walks you through exactly how to do it the right way — where to sell, how to price, and what to avoid.
Keep some, sell the rest — maybe there's a coin from the year a family member was born, or something that feels like it meant something to the person who collected it. There's no rule that says you have to sell everything. Set aside anything sentimental before you make any decisions.
Get into it yourself — this happens more than you'd think. People inherit a collection, start learning about what they have, and end up completely hooked. If you find yourself genuinely curious about what you're holding, that's worth paying attention to.
You don't have to decide right now. The coins aren't going anywhere.
A Word on the Weight of All This
I want to take a second to say something that doesn't usually make it into guides like this.
Going through someone else's collection can feel strange. These were someone's treasures. They spent real time building this — sometimes over decades — and now it's in your hands. That can come with a lot of feelings. A little sadness, maybe some guilt about thinking of selling.
I want you to know that handling this thoughtfully — taking your time, doing your research, making informed decisions — is itself a form of respect for what they built.
There's no rush. Do it at your own pace.
Your First 48 Hours — A Simple Checklist
If you're feeling overwhelmed, here's all you need to do right now:
Don't clean anything
Sort coins into rough groups
Look for paperwork or documentation
Check dates on dimes, quarters, and half dollars — 1964 and earlier means silver
Set aside any professionally graded coins in plastic slabs
Do a little research before talking to any dealers
That's it. One step at a time.
