This is an amazing skeleton concept coin of the Panama Balboa proof silver coin.  Perfect for collectors but also for a gift to coin lovers.

The balboa is, along with the United States dollar, one of the official currencies of Panama. It is named in honor of the Spanish explorer/conquistador Vasco Núñez de Balboa. The balboa is subdivided into 100 centésimos.

The balboa replaced the Colombian peso in 1904 following the country's independence. With the exception of a fluctuation in 2016, the balboa has been tied to the United States dollar (which is also legal tender in Panama) at an exchange rate of 1:1 since its introduction and has always circulated alongside dollars.
