| 裏面の説明 | A large sea turtle (tartaruga do mar) is depicted in finely detailed high relief, shown in a three-quarter view swimming amid an underwater scene of corals and sea grasses that fill the field. Two smaller sea turtles and a fish appear in the upper left portion of the field, adding depth to the marine composition. The legend 'TARTARUGA DO MAR - S. TOMÉ E PRÍNCIPE' arcs around the upper periphery, while the denomination '3500 DOBRAS' is inscribed along the lower periphery, both flanked by raised bullet points. The overall design is rendered in proof quality with frosted devices set against a mirror-polished field, emphasizing the naturalistic detail of the wildlife subject. |

São Tomé e Príncipe issued this piece as part of a wave of large-format silver wildlife coins that flooded the collector market in the late 1980s and early 1990s, when small nations with thin mint infrastructure routinely contracted foreign minting houses — likely Valcambi or a comparable Swiss or German facility — to produce high-value numismatic issues with no genuine domestic circulation intent. The 3500 Dobras denomination was essentially fictional in purchasing-power terms for the local economy at the time.
The islands' genuine conservation record is notable — the endemic fauna of the Gulf of Guinea had attracted international attention by this period — but the coin's origins are commercial rather than policy-driven.
