Collection Value Tracker

A collection is more than a list of items — it is a portfolio. MPC's collection value tracker gives you portfolio-level analytics for your collectibles: total value, cost basis, ROI, value over time, category breakdowns, and top performers. It is the same kind of performance tracking that investors expect from their brokerage accounts, built for collectibles.

Portfolio Analytics for Collectors

• •Total collection value — updated as individual item values change
• •Total cost basis — what you paid for everything
• •ROI — total return on your collection investment
• •Value-over-time chart — how your collection's worth has changed
• •Category breakdown — value by collectible type
• •Collection breakdown — value by sub-collection
• •Top performers — items with the highest value gains
• •Health score — a composite measure of how well-documented your collection is

Automatic Monthly Re-Valuation

MPC automatically re-values your items every month, keeping your portfolio tracking current without any manual effort. Each re-valuation is recorded in the item's price history, so you can see exactly when values changed and by how much.

Make Informed Decisions

With portfolio tracking, you can see which categories are driving your collection's growth, which items might be worth selling, and where you have concentration risk. This is the kind of insight that turns a collection from a hobby into a managed portfolio.

Key Portfolio Metrics for Collectors

• •Total estimated asset value of the collection
• •Year-over-year growth percentage across categories
• •Liquidity score based on current market interest
• •Asset allocation by rarity and item class
• •Historical high and low valuation records
• •Volatility index for high-risk assets

Learning to read value-over-time charts is essential for long-term collection management. These visual tools typically plot your portfolio's net worth against historical market benchmarks to show how your assets have performed relative to broader industry trends. A rising slope indicates a healthy appreciation in value, while dips often highlight broader market corrections that might represent great buying opportunities. By analyzing these charts, you can pinpoint exactly when your collection peaked or dipped, allowing you to deduce correlations with external events. It is important to filter these charts by specific timeframes — weekly, monthly, or yearly — to distinguish between short-term noise and significant, long-term trends. By mastering these visualizations, you transform from a casual collector into a strategic investor who understands the pulse of their portfolio and can make calculated, data-informed decisions about when to hold or sell.
