Market Value Tracking

Magpie can look up current market prices for your items from multiple sources, helping you track their value over time. Whether you collect vinyl records, trading cards, or anything else, price estimates give you a clear picture of what your items are worth today and how that value has changed.

Supported Price Sources

Source	Available For	What You Get
eBay	All collection types	Average, median, min/max prices from completed eBay listings
Discogs	Vinyl Records collections	Marketplace pricing from the world's largest music database
Scryfall	Trading Cards collections	TCGPlayer pricing data for Magic: The Gathering and other trading card games

Which sources are available depends on your collection template. Every collection can use eBay, while Discogs and Scryfall appear only for their respective collection types.

Looking Up Prices

1. Open an item in your collection
2. Click Price Estimates (or tap on mobile)
3. If multiple sources are available, select a source tab (e.g., eBay, Discogs, or Scryfall)
4. Enter a search query -- your item name is pre-filled, but you can refine it
5. Click Search [Source Name]
6. Review the results showing the average price, price range, and number of listings found

Price History & Trends

Each time you fetch a price, Magpie saves the result to build a history for that item. Over time, this gives you a clear view of how your item's market value is changing.

• The Price Trend chart shows how prices have moved over time
• Choose a time range to focus on: 30 Days, 90 Days, or 1 Year
• A trend indicator shows whether the price is going up, down, or staying stable, along with a percentage change
• Fetch prices periodically to build a more complete and accurate history

Comparing Sources

When multiple price sources are available for your item, you can compare them side by side.

• The All Sources section displays each source's latest price and trend together
• This helps you understand the fair market value across different marketplaces
• Differences between sources are normal -- each marketplace has its own buyer and seller community

Using a Price Estimate as Your Item Value

After fetching a price estimate, you can apply it directly to your item:

1. Click Use as Value on any price estimate
2. The average price will be set as your item's current value
3. This automatically updates your collection totals and portfolio analytics

Manual Estimates

If you have your own appraisal or want to record a price from a source Magpie doesn't track, you can add it manually.

1. Scroll down to the Manual Estimates section
2. Click Add Manual Estimate
3. Enter your price information
4. Manual estimates appear alongside market data in your price history

Mobile App

On the Magpie mobile app:

• Price trend badges appear on the item detail screen, showing the latest price and trend for each available source
• Tap a badge to open the full price estimate view
• The Price Estimates button gives you access to the full search and comparison features, just like on the web

Tips

• Fetch prices regularly to build accurate trend data -- monthly or after major market events works well
• Use specific search terms for better results. Include details like edition, condition, or year
• Compare multiple sources when available to get a well-rounded value assessment
• Vinyl records: Including the catalog number in your search can improve result accuracy
• Trading cards: Including the set name helps find the exact printing you own
• eBay results reflect completed (sold) listings, so they represent actual market prices rather than asking prices
