Sports cards and collectibles are more than just a childhood pastime. For entrepreneurs who understand the market, they can become the foundation of a profitable business with significant growth potential.
DJ Sports Cards is an example of how a personal passion can evolve into a serious retail operation. Its founder, Don Josh, started small, working with limited capital and gradually building a business that generates high six-figure annual revenue through a combination of in-store sales and online channels.
His experience offers practical lessons for aspiring entrepreneurs, from pricing collectibles and managing inventory to attracting customers without relying heavily on paid advertising. It also highlights an important principle: long-term success often comes from building trust and community, not simply selling products at the lowest price.

📌 Key Takeaways
- Start with a small budget: Test the market through local card shows, online marketplaces, and community events before committing to a permanent retail location. Reinvest profits to expand inventory gradually.
- Combine physical retail with e-commerce: A brick-and-mortar store can offer a personal shopping experience, while online marketplaces help reach collectors worldwide and move specialized inventory.
- Protect your profit margins: Competing exclusively on price can undermine a business. Set prices based on market demand, acquisition costs, and operating expenses rather than trying to be the cheapest seller.
- Use organic marketing: Regular website updates, social media activity, and customer loyalty initiatives can generate repeat business without requiring a large advertising budget.
- Build a reputation for fair deals: Transparent collection purchases and realistic valuations encourage collectors to return and recommend the store to others.
How to Build a Business Around Collectible Sports Cards
1. Start Small and Reinvest Your Profits
DJ Sports Cards began with a modest investment. Don Josh started selling cards while still in school, eventually selling his personal collection for approximately $500. He then used the proceeds to acquire part of a local store's inventory and began contributing toward the rent.
Rather than treating early earnings as disposable income, he put the money back into the business. Additional income from other work helped fund more collection purchases, card-storage supplies, and unopened packs.
This approach illustrates a practical way to enter a collectibles market without taking on substantial debt or committing to a large initial investment.
Advice for aspiring entrepreneurs: You do not need a fully equipped store to get started. Test demand at local trading card shows, through online marketplaces, or by selling directly to collectors. Learn which products move quickly, understand your costs, and expand only when the numbers support it.
2. Price Inventory Strategically and Understand Your Margins
One of the most common mistakes new collectibles sellers make is trying to offer the lowest prices in the market. While competitive pricing matters, consistently underpricing inventory can leave too little money to cover rent, labor, payment processing, shipping, and other operating expenses.
Understand the difference between markup and margin. If you purchase a card for $100 and sell it for $150, your gross profit is $50. Your gross margin is 33.3% of the selling price, while your markup on cost is 50%.
That distinction matters when setting financial targets. A gross margin of approximately 33% may be a useful planning benchmark for some products, but it is not a universal minimum. The right target depends on the product category, sales velocity, overhead, and the amount of work required to prepare inventory for sale.
Base valuations on completed sales. An asking price does not necessarily reflect what a buyer is willing to pay. Check recent completed transactions on platforms such as eBay and use specialized pricing tools where appropriate. Adjust for the card's condition, grading, rarity, demand, and recent market movements.
For example, a highly sought-after Michael Jordan card with an established market value of $4,000 may justify a relatively aggressive acquisition offer if buyers are actively looking for it. A dealer might offer 50% to 75% of estimated resale value for certain desirable cards, depending on liquidity and risk. However, this range should not be treated as a universal rule.
Bulk collections require a different calculation. Lower-value cards can take considerable time to sort, identify, price, and list. The purchase price should account for that labor, the proportion of cards likely to sell, and the possibility that some inventory may remain unsold.
The objective is not simply to buy low and sell high. It is to understand the economics of each transaction and maintain enough gross profit to support a sustainable operation.
3. Market Your Store Without a Large Advertising Budget
Paid advertising is not the only way to attract customers. A collectibles business can build visibility and encourage repeat visits through consistent content, useful online information, and experiences that give people a reason to return.
📈 Keep Your Website Updated
Publishing new inventory, adding accurate product descriptions, and maintaining useful category pages can help potential customers discover a store through search engines. Individual product pages may also attract buyers searching for specific players, sets, or collectible items.
However, adding new listings every day does not automatically improve search rankings. Strong SEO depends on factors such as useful content, clear site structure, page performance, relevant search terms, and a positive user experience.
For an online collectibles store, accurate inventory information and well-organized product pages can serve two purposes: helping search engines understand the site and making it easier for customers to find what they want.
🎁 Create a Kids Club
A family-friendly loyalty program can turn an ordinary shopping trip into a recurring experience. One approach is to give children a membership card that allows them to claim a small reward, such as a sports card or a miniature building toy, each month.
The reward does not have to be expensive to make an impression. The real value comes from creating a reason for families to visit again, giving children something to look forward to, and making the store feel welcoming to newcomers.
Over time, these small interactions can help establish relationships with families and encourage word-of-mouth recommendations.
🕹️ Make the Store an Experience
Physical retail can offer something that a standard product listing cannot: the opportunity to browse, discover unexpected items, meet other collectors, and share an interest with friends or family.
Free arcade games, accessible displays, and complementary collectibles such as LEGO products or Beanie Babies can make a store more engaging for visitors with different interests.
The key is to create an environment where customers want to spend time. Every additional attraction should still make financial sense, but a thoughtfully designed store can become a destination rather than just another place to buy products.
4. Combine a Physical Store With Online Marketplaces
A hybrid retail model allows a collectibles business to benefit from personal relationships and a broader online audience. Each channel serves a different purpose, and the strongest strategy is to understand how they complement one another.
🏪 Physical Retail: Community and Personal Relationships
A brick-and-mortar store gives collectors a place to inspect cards in person, discuss valuations, trade items, and discover products they might not have searched for online.
It also creates opportunities to purchase collections directly from customers. These transactions can become a valuable source of inventory, particularly when sellers prefer a straightforward local sale over the time and effort involved in listing individual cards themselves.
For this model to work, the store must provide enough value to justify its overhead. Rent, staffing, utilities, insurance, and inventory requirements all need to be reflected in the business plan.
🌐 E-commerce: Reach Beyond Your Local Market
Online marketplaces such as eBay and specialist collectibles platforms such as Beckett can help sellers reach buyers outside their immediate geographic area.
Online channels are particularly useful for rare cards, niche products, and items that may not attract enough interest from local shoppers. They can also provide useful market data when researching comparable sales.
However, online selling comes with its own costs, including marketplace fees, shipping materials, postage, returns, and the time required to photograph, list, and fulfill orders. Sellers should also keep inventory records synchronized across channels to avoid selling the same item twice.
A practical strategy is to use the physical store to build relationships and source inventory while using online channels to expand the potential customer base. The right balance depends on customer demand, product mix, and the economics of each sales channel.
💡 Final Thoughts
The DJ Sports Cards story illustrates how a personal interest can develop into a substantial business through disciplined financial management, market knowledge, and a focus on customer relationships.
You do not necessarily need a large initial investment to enter the collectibles market. You do, however, need to understand what customers value, buy inventory carefully, price products with operating costs in mind, and reinvest profits strategically.
For entrepreneurs considering a similar venture, the most important lessons are straightforward:
- Start small and validate demand before taking on high fixed costs.
- Use completed sales and real market data to make purchasing and pricing decisions.
- Track gross margins, inventory turnover, and operating expenses.
- Build organic visibility through useful content and consistent online merchandising.
- Create customer experiences that encourage repeat visits and referrals.
- Be transparent when purchasing collections and realistic about resale values.
Passion can provide the motivation to get started, but sustainable growth comes from sound business fundamentals. When a genuine interest is paired with careful buying, thoughtful pricing, and a loyal customer community, a hobby can become much more than a side project.
