Issued to mark Nigeria's fiftieth anniversary of independence from Britain, achieved on October 1, 1960. The 1000 Naira denomination is purely notional — no circulating coin of that value existed then or now, and the face value bears no relationship to the silver content or the coin's actual market price.
The specifications mirror the Commonwealth crown-sized format adopted by dozens of issuing authorities for commemorative purposes, with the 28.28g/.925 standard effectively set by the Royal Mint and widely licensed outward. Nigeria's commemorative program in this period was administered through external minting contractors rather than the Nigerian Security Printing and Minting Company.
