Heritage Auctions opened bidding on the ID card at $2,000. It was sold for $30,000 (£24,041) after 30 bids.

The badge was issued to Shakur on 28 February 1995 by the State of New York Department of Correctional Services.

Earlier this month a breakup letter written by Shakur to Madonna went on sale with a starting price of $100,000. The bidding ends tomorrow (26 July).

The breakup letter is up for auction now via gottahaverockandroll.com. A portion of the proceeds will be donated to breastcancer.org.
