Ace of Diamonds: Why Is This Card the Bellwether of the Card Series Market?
Among the entire Hanyu Card Series, the Ace of Diamonds is the most frequently seen card in international auction houses. Bonhams, Sotheby's, and Whisky Auctioneer almost consistently record its transactions annually, leading buyers and sellers to habitually use it as a reference point for gauging the trends of the entire Card Series. This characteristic of being "visible to everyone and having prices known to everyone" paradoxically makes it one of the easiest single cards to liquidate when one possesses it.
About Hanyu and the Card Series
Hanyu is a single malt distillery located in Saitama Prefecture, Japan, which ceased production and closed down as early as 2000. When the distillery changed hands, the original whisky was almost discarded. It was Ichiro Akuto who stepped in to rescue the last batch of casks, which later led to the world-renowned Ichiro's Malt.
The concept of the Card Series was to bottle these salvaged original whiskies in single cask format in batches, naming them after playing card suits and ranks. The entire series was issued between 2005 and 2014. Since each card corresponds to an independent cask and is bottled until empty, the entire series cannot be replenished by its very nature—this is the fundamental reason for the value of individual cards like the Ace of Diamonds.
