| 背面描述 | A Siberian crane (Leucogeranus leucogeranus) is depicted in left profile, its long neck bent downward as it forages among stylised wetland reeds and grasses rendered across the field in a naturalistic composition. The design employs a contrasting matte and proof finish to distinguish the bird from the darkened background, highlighting the fine feather detail on the wings and body. The Arabic numeral '۵۰۰' appears in the lower right field, with the denomination legend 'افغانی' (Afghani) inscribed below, completing the denomination statement across the lower portion of the reverse. |

Afghanistan issued this coin in 1978 under the short-lived Daoud Khan republic, just months before the April Saur Revolution brought a Soviet-backed communist government to power — making this one of the final numismatic products of that administration. The Siberian crane (Leucogeranus leucogeranus) was listed by the IUCN as endangered at the time, and its appearance here reflects the WWF-linked wildlife conservation series that circulated through several issuing authorities during the late 1970s.
The dual KM references indicate proof and uncirculated variants were struck separately, a common arrangement for these limited-issue conservation pieces produced primarily for the collector export market rather than domestic circulation.
