Old Coin Collections: My 4-Step Profit Blueprint for 2025
How do you buy and sell old coin collections?
It took me three years to get my hands on this coin collection:
And while that might sound like an exaggeration, it’s actually par for the course in the world of coin collecting.
The truth is, buying an old coin collection often involves more than just money—it requires patience, persistence, and a strong network. I’m going to use this experience as an example to give you a step-by-step guide on how to buy an old coin collection, so you can start building your own coin business or side hustle in 2025 and beyond.
Step 1: Build Your Network
When I first started out in coin collecting, I didn’t know anyone in the field. I didn’t have any insider information, connections, or even a clue about where to find valuable coins. Like many collectors, I began by scouring garage sales. Every weekend, I would visit up to 50 garage sales a day, asking the same question at each one: “Do you have any old coins for sale?”
Most of the time, the answer was no. Occasionally, someone would say they had some coins but didn’t have the time to bring them out. When that happened, I’d leave my phone number, hoping they’d call me later. But, in the beginning, I got zero callbacks—literally none. It was disheartening, and I started to think that this approach wasn’t going to work.
That’s when I decided to print some business cards. I made sure they clearly stated that I was interested in buying coins, silver, and gold. Every time someone mentioned they had coins but weren’t ready to sell, I’d hand them a card and tell them to call me whenever they were ready. This simple change made a huge difference. Even though most people still didn’t call right away, I started getting calls two to three years later from people who had kept my card. That’s exactly how I ended up with this particular collection of Israeli silver coins.
Three years after handing out my business card, the seller called me up out of the blue. He said he had a collection he was finally ready to sell, and because of the relationship we had built over the years, I was the first person he thought of. The lesson here is clear: building a network takes time, but it’s absolutely essential if you want to succeed in this business.
Step 2: What to Look for When Collecting Coins
Once you’ve finally made the connection and have the opportunity to buy a collection, the real work begins. Evaluating the collection carefully is crucial, not just to ensure you’re getting a good deal, but also to understand what you’re actually buying. When I first got my hands on the Israeli silver coin collection, I knew I needed to take my time to assess each coin thoroughly.
One of the most important things to do when evaluating a collection is to check the condition of the coins. For example, in this collection, most of the coins were in good shape, but some had significant issues due to being stored in PVC holders. These holders, while common, can cause a green, ugly patina on coins, a result of chemical reactions over time. This can severely affect the numismatic value of a coin.
Take, for example, the Hanukkah coins in the collection. These coins are part of a popular series issued by Israel in the 1970s and 1980s, featuring menorahs from various Jewish traditions around the world. While these coins are valuable, their worth varies significantly depending on their metal content—some are 50% silver, some 90% silver, and others are just cupronickel.
Without the original cards or documentation, it’s essential to weigh the coins and examine them closely to determine their metal content.
In this particular collection, the PVC damage meant that some coins had their numismatic value significantly reduced.
When you come across issues like this, it’s important to factor them into your valuation. For these coins, I had to consider them mostly for their silver content rather than their collectible value.
But even with these issues, this collection had a lot of value. There were several Morgan dollars hidden among the Israeli coins—unexpected finds that added to the overall worth of the collection. Discoveries like this are why it’s so important to go through every coin carefully, even when the collection seems straightforward at first glance.
The takeaway here is simple: don’t rush the evaluation process. Look at each coin individually, understand its condition, and be aware of any issues that could affect its value. This careful assessment will help you make an informed decision about how much to offer and what you can expect to make from the collection.
Step 3: How to Sell a Coin Collection
Once you’ve thoroughly evaluated the collection, the next step is to negotiate a fair price. This part of the process can be tricky, especially when you’re dealing with someone you’ve built a relationship with over the years. However, it’s crucial to strike a balance between getting a good deal for yourself and ensuring the seller feels they’re being treated fairly.
In the case of the Israeli silver coin collection, I knew I had to offer a price that reflected the current value of the coins while considering the issues like PVC damage. I typically aim to pay about 70% of the collection’s value, and that’s what I offered in this deal. This percentage allows me to make a profit after accounting for selling fees, which usually run around 10%, whether I’m selling on Whatnot, eBay, or another platform.
SILVERPICKER PRO TIP: One thing I’ve learned over the years is that transparency during the negotiation process is key. I’m upfront with sellers about why I’m offering a particular price, explaining the factors that influence the value, such as the condition of the coins and current market prices. In this instance, I explained the impact of PVC damage on the coins’ numismatic value, which helped the seller understand why my offer was lower than they might have expected.
It’s also important to remember that this isn’t just a one-time transaction; it’s part of building a long-term relationship. By offering a fair price, you not only secure this deal but also open the door for future opportunities. The seller of this collection was happy with the price I offered, and because of that, he has since referred me to others who had collections to sell. These referrals have led to additional deals, further expanding my network and my business.
One critical piece of advice I’d offer to anyone getting into the coin business is to avoid the temptation to lowball sellers. Sure, you might make a quick profit in the short term, but you’ll burn bridges and lose out on long-term opportunities. In the coin collecting world, your reputation is everything. By consistently offering fair deals, you build trust, which is the foundation for a successful business in this field.
Step 4: Close the Deal and Look Ahead
Once the negotiation is complete and both parties have agreed on a fair price, it’s time to close the deal. But even at this stage, there are important considerations to keep in mind to ensure the transaction goes smoothly and sets the stage for future opportunities.
In the case of the Israeli silver coin collection, after agreeing on the price, we finalized the terms of the purchase. One of the benefits of building a strong relationship with the seller is the level of trust that develops. In this instance, the seller allowed me to take the collection home to review it thoroughly before finalizing the payment. This kind of arrangement wouldn’t be possible without the trust we had established over the years.
When closing a deal, it’s essential to make sure all the details are clear. This includes agreeing on how and when payment will be made, what happens if any issues are found upon further inspection, and how the coins will be delivered or transferred. For this deal, I reviewed the coins at home and then completed the payment, confident that we both understood and agreed to the terms.
Silverpicker pro tip: Closing the deal is not the end of the relationship—it’s the beginning of a new phase. By treating the seller fairly and professionally, you open the door to future opportunities. In this case, after I bought the initial collection, the seller referred me to others who had coins to sell, which led to additional purchases. A year later, he even found another part of his father’s collection and offered it to me first. This is the power of referrals and the network effect in action.
Looking ahead, it’s important to keep in touch with the seller. A simple follow-up message thanking them for the deal can go a long way in maintaining the relationship. Let them know you’re still interested in buying coins and that you’d appreciate any referrals they can provide. This keeps you top of mind the next time they or someone they know is looking to sell.
Additionally, plan how you’ll sell the coins you’ve acquired. Whether you’re using platforms like Whatnot, eBay, or another marketplace, ensure you’re prepared to market the coins effectively and account for any selling fees in your pricing strategy. In my case, I often sell coins from my collections in Whatnot auctions, starting bids at $1 to generate interest and drive competitive bidding. This approach not only helps me move inventory quickly but also attracts a wide range of buyers.
The Bottom Line: How to Make Money Coin Collecting in 2025
Buying an old coin collection is not just about finding a deal—it’s about building a network, being persistent, carefully evaluating what you’re buying, negotiating fairly, and closing the deal in a way that sets you up for future success. My experience with the Israeli silver coin collection, which took three years to acquire, perfectly illustrates the patience and effort required in this business. But it also shows the rewards that come from sticking with it and doing things the right way.
To recap:
- Build Your Network: Start by letting people know you’re interested in buying coins. Use business cards and attend garage sales, flea markets, and other events to make connections. Remember, networking takes time, but the relationships you build will pay off in the long run.
- Evaluate Carefully: When you finally get the chance to buy a collection, take your time to assess each coin. Understand the condition, metal content, and any issues that might affect value. This careful evaluation is key to making a smart purchase.
- Negotiate Fairly: Offer a price that reflects the true value of the coins, considering their condition and market trends. Transparency and fairness will help you build trust with the seller, leading to future opportunities.
- Close the Deal and Look Ahead: Finalize the transaction clearly and professionally, and keep the relationship alive for future deals. Referrals and repeat business are the lifeblood of a successful coin collecting business.
