BOTSWANA. 150 Pula, 1978. PCGS PROOF-70 DEEP CAMEO Gold Shield.Fr-3; KM-13. Conservation Series issue featuring the Brown Hyena with a mintage of only 219 pieces in Proof. A flawless presentation, showcasing unbroken frost atop the raised surfaces and peerless reflectivity in the fields, undiminished by spots, tone or haze. Quite possibly entirely without duplication in this ultimate quality, with this being the only PROOF-70 graded by either PCGS or NGC. An incredibly important offering in this quality, as this short-lived series, dedicated to the conservation of wildlife, is perhaps the most universally appreciated of all modern issues.<p><p>
