As of 2025, Ken Goldin's estimated net worth stands at approximately $350 million. This substantial wealth is primarily attributed to the success of Goldin Auctions, the premier platform for high-value sports memorabilia and collectibles, which he founded in 2012. The company's impressive sales, including record-breaking auctions like the 1952 Mickey Mantle rookie card sold for over $12 million, have significantly contributed to Goldin's financial stature.
