LEONARD Nimoy fans could “live long and prosper” with a limited edition coin that pays tribute to his iconic character Spock from Star Trek: The Original Series.

The Perth Mint coins are emblazoned with a colour image of Spock, the logical alien with his trademark pointed ears and famous split-finger Vulcan salute, against a backdrop of the IDIC Vulcan symbol.

Priced at $115 each, the 5000 limited edition coins come inside Star Trek-inspired display cases and are accompanied by numbered certificates of authenticity.

Each coin is struck from one ounce of 99.9 per cent pure silver and is issued as legal tender under the authority of the Tuvalu government.
