The C3 Card Compare tool lets you put two cards side by side and see their current Australian prices, 14-day price trend, and buy versus sell spread. It covers MTG, Pokemon, Lorcana, One Piece, Yu-Gi-Oh, Dragon Ball Super, Star Wars Unlimited, and Riftbound.
This guide explains what each number means and how to use the tool to make better buying and selling decisions.
Quick Answer
Go to /compare, search for any card by name, add a second card, and compare. The tool shows current eBay AU sold prices, a 14-day trend line, and Card Kingdom buylist data for MTG. Use it before buying any single card worth more than AU$10.
What the C3 Card Compare Tool Shows
Current AUD Price
The price shown is derived from eBay AU recently sold listings for that card in near mint condition. This is the actual Australian market price: what Australian sellers have received for that card in the last two weeks, not a conversion from a US database.
Australian prices differ from US prices for several reasons: import costs, the AUD/USD exchange rate, and local supply and demand. The C3 Card Vault and Compare tool use Australian sold data rather than US-based estimates. See our AU vs US pricing explainer for why the gap exists.
14-Day Price Trend
The trend indicator shows whether the card's AUD price has moved up, down, or stayed flat over the past two weeks. A rising trend suggests increasing demand: possibly from tournament results, a reprint announcement removing the reprint fear, or content creator attention. A falling trend suggests the opposite.
Use the trend when timing a purchase. A card falling in price over two weeks is worth waiting on if you're not in a hurry. A card rising sharply may be worth buying before it moves further: or avoiding if it's a speculative spike that tends to correct.
Card Kingdom Buylist (MTG Only)
For MTG cards, the tool shows the current Card Kingdom buylist price in USD. Card Kingdom is one of the largest MTG single card buyers in the world, and their buylist represents a reliable baseline for what the card is worth to a buyer who pays cash.
The spread between the eBay AU sell price and the Card Kingdom buylist (converted to AUD) shows how much margin exists between what you can sell a card for and what a professional buyer will pay for it.
How to Use It: Three Common Scenarios
Scenario 1: Deciding Which Card to Buy
You want either Sol Ring or Arcane Signet for your Commander deck. Both provide ramp. The question is which gives better value at current Australian prices.
Open the Compare tool. Search Sol Ring. Add Arcane Signet. The tool shows both current AUD prices side by side. The cheaper option for equivalent function is the right buy unless there is a specific reason you need one over the other.
Scenario 2: Timing a Card Purchase
You have been tracking Maha, Its Feathers Night from Bloomburrow. It spiked when someone posted a powerful combo deck. You think the spike is temporary.
Use the 14-day trend. If the price is still climbing, the market hasn't settled. If the trend has flattened or is dropping, the spike is correcting and buying now captures better value than buying at peak.
Scenario 3: Checking Sell Value Before Listing on eBay
You have a card you want to sell and need to set the right price. Search it in the Compare tool. The current price shows what recent sellers have received. Set your listing price within that range: slightly above if your copy is particularly clean, slightly below if you want a quick sale.
For MTG, also check the Card Kingdom buylist figure. If the buylist number (converted to AUD) is close to the eBay sell price after fees, selling directly to Card Kingdom (or a local store with equivalent buylist pricing) may be easier than managing an eBay listing.
Which TCGs Are Supported
The Compare tool covers:
- MTG: Full card database including alternate arts, foil prices, and Card Kingdom buylist integration
- Pokemon: All sets from the Scarlet and Violet era and earlier available
- Lorcana: All sets including Wilds Unknown
- One Piece: All English sets
- Yu-Gi-Oh: Current and recent sets
- Dragon Ball Super: Available sets
- Star Wars Unlimited: All released sets
- Riftbound: Origins, Spiritforged, and Unleashed
What the Tool Doesn't Show
Condition adjustments: The price shown assumes near mint condition. Lightly Played (LP) cards typically sell for 10-15% below near mint. Moderately Played (MP) cards typically sell for 20-35% below near mint. Adjust your expectations accordingly for played copies.
Real-time live prices: Prices update regularly from eBay AU sold data but are not a live feed. A card that spikes dramatically today may not reflect in the tool for 24 to 48 hours.
Graded card prices: PSA-graded or BGS-graded cards sell at significant premiums over raw near mint. The tool shows raw ungraded prices.
The Compare Tool vs Just Checking eBay
Checking eBay directly for a single card is clear. The Compare tool adds value when:
- Comparing two cards: eBay requires opening two tabs and manually comparing; the Compare tool shows both simultaneously
- Tracking a trend: eBay shows current listings but not historical sold data as clearly; the Compare tool's trend line shows direction at a glance
- MTG buylist context: The Card Kingdom buylist integration is not available from eBay search
For quick checks on a single card, eBay sold listings remain the most granular data source. The Compare tool is most useful when making a decision between options.

The C3 Take
The decisions you make with your TCG collection matter more than most guides suggest. Whether you are buying, selling, or holding, the difference between a good outcome and a poor one almost always comes down to checking current AUD prices before you act. Use the live data at /cards/mtg to make price-informed decisions every time.
