Quick Answer
The C3 Collection Tracker at /tracker is a free downloadable Google Sheets template that tracks your TCG collection across eight games with automatic value calculations. This guide explains how to set it up, log your first cards, and use it to make smarter buying and selling decisions.
Downloading and Setting Up
Go to /tracker and download the free tracker. In Google Sheets, go to File > Make a Copy to save it to your own Google Drive account. Making a copy ensures you have your own editable version that does not overwrite the template. The tracker covers MTG, Pokemon, Lorcana, One Piece, Yu-Gi-Oh, Dragon Ball Super, Star Wars Unlimited, and Riftbound across separate tabs.
Logging Your First Cards
In each game's tab, enter card name, set, quantity, condition (NM/LP/MP), and your purchase price. The tracker has a current value column that you update periodically from /cards/mtg or the relevant game hub. The profit or loss column calculates automatically from your purchase price versus current value. Start with your 20 most valuable cards across all games to establish the baseline.
Updating Card Prices
Update current prices monthly for most collectors and weekly for active buyers and sellers. For each price update, check the relevant game hub at /cards/mtg or the corresponding hub for your game, then search each card name and enter the current AU market price. The tracker's summary tab shows total collection value, total investment, and total profit or loss after each update. Tracking this over time shows whether your collection is growing or shrinking in value.
Using the Wishlist Tab
The tracker includes a wishlist section where you can log cards you want with priority ranking and budget. When you have cash available to buy new cards, sort the wishlist by priority and budget to identify the highest-value purchase for your current spending limit. Cross-reference wishlist items with current prices at the game hubs to confirm you are paying a fair price before buying.
Before Selling a Card
Before listing any card for sale, update its current price in the tracker and check the profit or loss. This tells you exactly how the sale compares to your original investment and whether now is the right time to sell or whether holding makes more sense. Cards with significant appreciation are worth checking against the Market page at /market to see if the current price is near a peak or still rising.
Sharing and Backing Up
The Google Sheets format means your collection is automatically backed up in Google Drive. Share the tracker with a family member or fellow collector by clicking Share in Google Drive and entering their email. Sharing is useful for couples who build a collection together or for players who want a second set of eyes on their collection valuation.
How This Tool Fits the Full C3 Toolkit
The C3 tools are designed to work together as a complete decision-support system for Australian TCG collectors and players.
The EV Calculator at /tools answers the sealed product question: is this box worth opening at my purchase price? It uses current AU card prices to give a verdict before you commit to opening.
The Card Compare tool at /compare answers the singles question: how do these specific cards compare in current AUD value? It shows up to four cards side by side with price trends.
The Market page at /market answers the timing question: is this card's price moving up or down right now? It shows seven-day price trends for the Australian market.
The Collection Tracker at /tracker answers the portfolio question: what is my collection worth, and am I ahead or behind on my investment? It tracks purchase prices and current values across eight games.
Using all four tools together gives you visibility into sealed product value, individual card value, price timing, and overall collection performance simultaneously. No single tool gives the complete picture. The combination does.
Getting the Most Out of C3 as an Australian TCG Player
C3 is built specifically for Australian TCG players because Australian prices, community context, and market conditions differ meaningfully from international resources. Every tool on the site reflects AUD pricing from the Australian secondary market rather than USD prices converted at a rough exchange rate.
Use the /play quiz hub to find the right game for your situation. Use the card hubs at /cards/mtg and equivalent pages for your game to check prices before every transaction. Use the blog at /blog for Australian TCG event coverage, set reviews, and value analysis specific to the local market. Use the eBay store for singles from all eight games with Australian shipping.
The combination of live price data, analysis tools, and an active singles store makes C3 a complete resource for Australian TCG players across all spending levels and collecting goals.
The C3 Take
The collection tracker is only useful if you actually use it. The habit of logging cards within 24 hours of buying them and updating prices monthly takes less than 20 minutes total per month for most collections. That investment of time provides ongoing clarity about what your collection is worth and when to buy or sell that most TCG players in Australia completely lack.
