PTCG & OPCG Indices

MemeStrategy has launched the world’s first Trading Card Game (TCG) market benchmark index series. Developed by Grade10 and introduced following evaluation and professional guidance from professors at HKU Business School, the index series provides transparent, objective, and authoritative indicators of market trends. By addressing long-standing challenges in the traditional collectibles market, including pricing opacity and fragmented data, the launch marks a significant step towards the standardization of trading card assets and the adoption of a more data-driven market framework.

The three core indices strictly focus on cards graded PSA 10 GEM MINT (the highest grade):

• PTCG100 Index: Tracks the 100 most representative Pokémon PSA 10 GEM MINT collectible cards in the market.
• PTCG500 Index: Tracks the 500 most representative Pokémon PSA 10 GEM MINT collectible cards in the market.
• OPCG100 Index: Tracks the 100 most representative One Piece PSA 10 GEM MINT collectible cards in the market.

As high-quality collectible cards gain broader recognition as alternative assets, Grade10’s index series provides a unified, objective and data-driven benchmark for the trading card market. Built on completed transaction data from leading platforms across North America, Europe and Asia—including Alt.xyz, eBay and SNKRDUNK—the indices focus exclusively on PSA 10 GEM MINT cards to support consistency and comparability. Constituents are screened and weighted according to 90-day trading volume, while pricing is calculated using a 30-day rolling interquartile mean to help reduce the impact of anomalous transactions and subjective valuation bias. Rebalanced quarterly, with newly issued cards subject to a 90-day seasoning period before inclusion, the indices are designed to reflect market depth, liquidity and underlying trading dynamics with institutional-grade rigour.
