Watch List notes:

'Abbasid Caliphate. Al-Mu'tamid. AH 256-279 / AD 870-892. AV Dinar (25mm, 3.68 g, 7h). Al-Rafiqa mint. Dated AH 274 (AD 887/8). Citing the heir al-Mufawwad / Citing the second heir Ahmad b. al-Muwaffaq, swastika and letter z below. Bernardi 181Hn. Slightly ragged edge. Near EF.

For reasons unknown, dinars struck at al-Rafiqa in AH 274 carry a swastika in the field. This is usually found on the obverse; the present variety, on which the swastika appears below the reverse field, is appreciably rarer.
