750 Dinara Tyrannosaurus Rex

Bosnia and Herzegovina issued this coin in 1993 while actively at war — the siege of Sarajevo was in its second year, and the country's monetary infrastructure was in near-total collapse. The dinara itself would be abandoned entirely within a few years, replaced by the convertible mark in 1998. Coins like this were struck almost exclusively for the international collector market, generating hard currency the government desperately needed while domestic circulation of any metal coinage was essentially nonexistent.
