20 Dalasis Buffalos silver coin

The Gambia has issued wildlife-themed silver rounds under its own authority since the 1970s, a practice common among smaller nations whose collector coinage programs generate hard currency revenue rather than circulate domestically. At 65mm, this piece sits toward the upper end of what standard coin presses handle — large-format strikes of this diameter are frequently produced on medal presses, often by European contract mints working on behalf of the issuing central bank.
