2 Baht - Rama IX Year of the Trees

Issued to mark the International Year of the Trees, this commemorative was struck as Thailand was accelerating a national reforestation campaign under royal patronage — deforestation in the northern highlands had become acute enough by the mid-1980s that the Thai government had begun restricting commercial logging concessions. The coin's timing aligned with a broader UNEP initiative that year encouraging member states to issue public awareness material, coins among them.

Mintage figures for this type are not widely documented, though surviving examples in uncirculated condition are plentiful enough to suggest a generous commemorative run.
