Danish West Indies 1905
10 Cents / 50 Bits
2.50g, AR800
And from America's other Carribean territory we have this dime from 1905, when it was the Danish West Indies rather than the U.S. Virgin Islands.
It's denomination of 10 cents and weight fits in with an American dime, but its 800 alloy is that used by Denmark, and the "50 bits" a reference to the franc coinage system. Indeed, the reverse is somewhat similar to that of the French 50 centimes of the day, and the Danish West Indies Franc was pegged at par to the French Franc.
When the DWI was purchased by the US to become the USVI in 1917, the local currency was converted to USD at a slight discount of about 3%, meaning that unlike with Puerto Rico, the local currency likely disappeared soon after the changeover.
