My Indexes

Build your own index: pick the cards (any grade we price), choose a weighting scheme, and get a level chart — base 1,000 at inception, computed from the same daily price data that powers the official indexes. Make it public to share it, or keep it private. Free.

How it works

• 2 to 25 cards per index, each tracked in the grade you choose (ungraded through PSA 10 and the other 10-grades).
• Four weighting schemes — equal, value, turnover (flagship-style with a 10% cap), or fully custom percentages.
• Frozen at inception: quantities are fixed on the data day you create the index, so its level means something. Rebalancing is coming soon.
• Level chart from inception forward, plus a clearly labeled hypothetical pre-inception segment where full history exists.
• Compare against any official index or your other custom indexes, every series rebased to 100.
