5 Dollars Czech Republic

Liberia's early-2000s commemorative program was, bluntly, a licensing operation — the country issued coins for virtually every conceivable subject, nearly none intended for domestic circulation, with distribution handled entirely through European coin dealers and the Franklin Mint's competitors. This piece uses niobium, a refractory metal that produces distinctive interference colors when anodized, a technique pioneered for collector coinage by the Austrian Mint beginning in 2003.

The Czech Republic connection is curatorial, not political — Liberia held no particular diplomatic or historical relationship with Prague that prompted the issue.
