1000 Francs Guinéens Birch Leaf in Summer

Guinea's commemorative program has leaned heavily on nature-themed issues since the mid-2000s, largely aimed at the European collector market rather than domestic circulation. The 2017 birch leaf issue was produced at a European private mint — almost certainly in Germany or Poland — under contract, as Guinea maintains no functioning mint of its own. These coins are legal tender in name only; the issuing face value bears no relationship to silver melt or collector market price.
