The items, which have a combined estimated value running into the millions, include signed shoes, shorts and shirts Russell accumulated during a career in which he won 11 NBA titles — the last two as a player-coach and the first Black head coach in any U.S. major pro sport. The most valuable item — already over $400,000 in online bidding through Thursday afternoon — is expected to be the jersey Russell wore in his last game, in the 1969 NBA Finals against the Los Angeles Lakers.
