Nominee for Best Marketplace

My Card Post (MCP) is a subscription-based, peer-to-peer marketplace built by collectors, for collectors. Unlike traditional platforms that rely on transaction fees, MCP operates with no seller fees and uses a simple flat membership model.

The platform emphasizes the true culture of collecting: trading, conversation, and deal-making, rather than pure transaction volume. Its mission centers on a “collectors first” philosophy that pushes back against middlemen and gatekeepers while celebrating the community and social connections that make the hobby special.

By prioritizing trust, community, and accessibility, My Card Post offers a fresh alternative to traditional marketplaces, giving hobbyists a place to buy, sell, and trade through authentic, peer-driven experiences.
