Master the Market with Premium Features

• Multi-Source Sales Data: Sales are aggregated directly from eBay, Goldin, Heritage Auctions, and 1stPrint.net, giving you a complete, cross-platform view of the market instead of a single, incomplete source.

• Daily Market Updates: The market never sleeps. The database is updated once a day, ensuring that users always have the most recent sales figures at their fingertips.

• Price Evolution Charts: Visualize trends with "Price Over Time" graphs. Identify if a volume or magazine issue is peaking or if it's the perfect time to "buy the dip."

• Grade Distribution Insights: Understand the rarity of specific grades to justify premium pricing or negotiate better deals. (See a real example of how much a single grade step can add to the price in the price guide.)

• Obi Tracking: The tracker specifically monitors the "Obi" factor, showing exactly how much value a pristine spine wrap adds to a specific volume. (Why obi condition matters is explained in the price guide.)

• Zasshi Tracker: Now covering Japanese prepublication magazines too. Track key issues from titles like Weekly Shonen Jump, Weekly Shonen Magazine, and Nakayoshi, including landmark issues featuring first appearances and debuts of iconic manga series.

• Exclusive Database: Gain access to over 6,000+ tracked manga sales across 350+ unique series, plus a growing zasshi database, all updated daily. Please note that the database focuses exclusively on Japanese editions and lists only transactions above $50.

Log each volume with its purchase price, see the live estimated value pulled from real market sales, and watch your P&L update automatically. Includes allocation by series, top winners & losers, and a market trend sparkline for every volume you own.
