5 Dollars - Elizabeth II Circuit of the Americas

The Circuit of the Americas in Austin, Texas opened in 2012 as the first purpose-built Formula 1 venue in the United States, ending a long gap in American F1 hosting after Indianapolis dropped off the calendar following the 2007 debacle in which only six cars started due to a tire dispute. Solomon Islands has issued numerous shaped and oversized silver pieces under licensing arrangements that have little connection to the issuing territory — this coin's nominal issuer has no geographic or historical relationship to American motorsport whatsoever.

The 77.8g planchet places it in the two-troy-ounce category standard for this format of commemorative issue.
