![RRRR silver coin, bust / long legend, c.300s CE, Himyarite Kingdom, Arabia](http://www.numismall.com/cdn/shop/files/w55842_{width}x.jpg?v=1697388951)
Bust (?) // Monogram, a derivative of ḥḍr (𐩢 𐩳 𐩧) with seemingly with extra letters in fields. 9mm, 0.26 grams. Zeno 321316 (this coin).
The reverse has the ḥḍr (𐩢 𐩳 𐩧) monogram, the curved line with dots above and additional unread letters around. Unique and interesting.
Seems to be unpublished in Huth and elsewhere. Obviously from 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.
