1 Dollar - Elizabeth II Diwali Festival

The Perth Mint has issued a string of culturally themed silver dollars targeting collector markets in Southeast Asia and the Indian diaspora — Diwali editions among the most consistently produced. The 2018 issue falls within that commercial program, struck to .9999 fineness rather than the standard .999, a purity specification the Perth Mint began emphasizing aggressively in its bullion and collector lines during the mid-2010s as a marketing differentiator against the Royal Canadian Mint.

KM#400 attribution places it firmly in the modern commemorative run with no known die varieties or minting irregularities on record.
