For the first time in over 20 years, the Big Ten conference expanded in 2011, adding the University of Nebraska as the 12th member of the conference. This officially licensed, 2" diameter, solid brass coin was minted in recognition of this historical event. It comes packaged in a clear, airtight collector's case and highlights all 12 teams logos. It is the only authorized coin minted to commemorate this occasion. A must have for any collector!
