Two Months In: Real Profits and Practical Lessons from Selling 50,000 Pokémon Cards

Initial Setup: Inventory and Key Investments

The foundation of this business started with a large purchase of bulk Pokémon cards—around 45,000 to 50,000 cards, which cost about $1,500. To this, I added a second pillar of inventory: cards from my personal collection that I was ready to sell, valued at roughly $2,000. This gave me a starting inventory of about $3,500.

However, the biggest problem was turning this massive pile of cardboard into a digital inventory I could actually sell online. The initial sorting process took a very long time. This led to a significant early investment.

The First Major Challenge: Digitizing the Inventory

After getting the cards, they just sat there for months. The bottleneck was getting them into a digital format. To solve this, I invested in a card sorting machine for about $2,500. While it's not one of the $20,000 professional models, it has been a massive time-saver. With the machine, I was able to get the entire bulk inventory processed into a CSV file with card names and prices in about a week and a half.

With the initial card and machine costs, my total starting investment was closer to $5,000-$6,000. This is a realistic picture of what it can take to get a serious operation off the ground, though you can certainly start smaller by selling cards from your own collection first.

My Multi-Platform Selling Strategy

With a digital inventory ready, the next step was figuring out where to sell. I've broken my strategy down by card type:

• Single Cards ($1+): These are sold on Ricardo, which is the Swiss equivalent of eBay. For sellers in the US, this would be comparable to listing on eBay directly.
• Bulk Cards: These are listed on two major European platforms: Cardmarket and CardTrader. For US sellers, TCGplayer is the closest equivalent.

To manage the bulk listings across two platforms, I use a tool called TCG PowerTools. I upload my single CSV file, and it lists my inventory on both Cardmarket and CardTrader. Crucially, it automatically syncs sales, so if a card sells on one platform, it's removed from the other. This prevents double-selling and saves a lot of manual work.

A Deep Dive into the CardTrader Zero Workflow

CardTrader has been a surprisingly strong performer, even better than Cardmarket so far. A big part of this is their CardTrader Zero program. To qualify, you need a minimum of 1,000 bulk cards listed; I currently have 10,000 there. The program allows you to consolidate all your sales from the week into a single shipment to a CardTrader hub.

Initially, shipping to their main hub in Italy was expensive—around $20 per shipment. However, I learned that they have local hubs. By contacting their support, I found a hub in my own country, Switzerland, which dropped my weekly shipping cost to just $3. If you're in the US or elsewhere, it's worth asking them if a local hub is available.

What's Actually Selling? Bulk Card Sales Data

After a few weeks of sales, clear patterns have emerged in the bulk card data. Most of my profit is currently coming from bulk, not singles.

• Modern Sets: The big sellers are playable cards—both Pokémon and Trainers. There are about 10 modern cards worth $1-$2 that sell very frequently. Reverse holos, especially from 151, also sell well, typically for $1 to $3.
• Older Sets: I was surprised to see that for sets like Sun & Moon and Sword & Shield, regular common and uncommon cards sell very well, especially on CardTrader.
• What Doesn't Sell: Regular common and uncommon cards from modern sets move very slowly.

If you want to start, you can just start with listing those cards and you do not need to list like all the modern cards like normal commons and uncommon cards. So you are then quicker and you have nearly the same revenue.

Analyzing the Singles Market and Sell-Through Rate

For my more valuable single cards ($1 and up), I'm seeing a sell-through rate of 25%. This means that in a given month, I sell 25% of the cards I have listed. This is a very strong number, as 10-20% is generally considered good. My inventory of singles has grown from 100 cards to nearly 400 as I reinvest cash from sales into buying new collections, typically aiming to pay around 70% of market value.

The Financials: A Look at Weekly Profits

After eight weeks, the business is generating consistent, if modest, profits. Here is the weekly breakdown, after fees:

• CardTrader (Bulk): $65 profit/week
• Ricardo (Singles): $50 profit/week
• Cardmarket (Bulk): $40 profit/week

This adds up to $155 in profit per week, or around $620 per month. I'm spending about 5 hours per week fulfilling orders and managing the business. It's a decent side income for the time invested.

Key Learnings and Future Business Plans

Not every idea works. I tried creating small 'master sets' of common/uncommon/rare cards from modern sets, but they haven't sold at all. The next experiment is to list them on a larger platform like eBay to see if a wider audience helps.

My main focus for growth is to increase the sell-through rate even further. The plan is to implement a Shopify store to act as a central inventory hub. This would allow me to list my single cards across Ricardo, Cardmarket, and CardTrader simultaneously, hopefully pushing my sell-through rate towards 30%. I'm also focused on acquiring more older set bulk in Near Mint condition, as I only sell NM cards individually to keep buyers happy.

The setup takes a long time, but once the systems are in place, it becomes a manageable process of slowly increasing inventory and fulfilling orders. It's a grind, but a rewarding one.
