![RRRR silver coin, bust left/ HRDG, c.300s CE, Himyarite Kingdom, Arabia](http://www.numismall.com/cdn/shop/files/w55840_{width}x.jpg?v=1697388386)
Helmeted bust left // Monogrammed ḥrḍg (𐩢𐩧𐩳𐩴) or ḥrḏg (𐩢𐩧𐩹𐩴), "g" is upside down. 10mm, 0.37 grams. Zeno 321367 (this coin).
This coin is listed on Zeno. Extremely rare, the only known coin with this monogram (with "g" upside down), unpublished in Huth and elsewhere. Obviously related to the Himyarite WTR-series (though the WTR monogram is replaced with a bust on this type), variously given to Karib'īl Watār Yuhan'im or 'Amdān Bayān Yahaqbiḍ.
