Nicaea, Bithynia

Obverse:  Μ ΑΥΡ ΑΝΤΩΝΙΝΟϹ ΑΥΓ  (M AYP ANTwNINOC AVg) (M AyR ANTVNINOc AvG) laureate bust right. 

Reverse: ΝΙΚΑΙΕΩΝ (NIKAIEwN) (NIKAIEVN) Elephant covered with a saddle and harnessing, going to the right and ridden by a mahout who holds in each hand a hooked pivot. Note: From portrait and legend could be either Elagabalus or Caracalla. Nicaea used the same for both.  The diameter is 22.7 mm and is 5.23 g, die axis 200 deg.  Reference: Recueil General II, 1, 564, Sear GIC 3051, Von Aulock 7044, not in BMC XIII (Bithynia), RPC VI, 3127

Obverse:  Μ ΑΥΡ ΑΝΤΩΝΙΝΟϹ ΑΥΓ (slight chance of ΑΥΡΗ) Μ ΑVΡ ΑΝΤΩΝΙΝΟC ΑΥΓ (M AVP ANTwNINOC AYg) (M avp antVninoc ayG) bust right. 

Reverse: ΝΙΚΑΙΕΩΝ (NIKAIEwN) (nikaieVn) 3 legionary standards with the legend in between on 2 lines. The diameter is 20 mm and is 4.05 g, die axis 200 deg. Reference: similar to RecGen 571, BMC XIII (Bithynia) 93.  Similar in reference for below.  Most likely RPC VI, 3128, based on obverse picture.  Though there are at least 2 variations of where the reverse legend are located, the reverse legend layout seems similar to one example of RPC VI, 3092 (though the obverse doesn't)

Obverse: Μ ΑΥΡ ΑΝΤΩΝΙΝΟϹ ΑΥΓ (M AVP ANTwNINOC AYg) (M avp antVninoc ayG) laureate and cuirassed bust of Elagabalus, right, seen from rear. 

Reverse: ΝΙΚΑΙΕΩΝ (NIKAIEwN) (nikaieVn) 3 legionary standards with the legend in between. The diameter is 25 mm and is 7.28 g, die axis 45 deg. Reference: RecGen 571, BMC XIII (Bithynia) 93.  Seems to match multiple examples without an reference at Roman Provincial Coins Online, possibly RecGen 571, RPC VI, 3124

Obverse: Μ ΑΥΡΗ ΑΝΤΩΝΙΝΟϹ ΑΥΓ  (M AYPH ANTwNINOC AVg)(M AyRh ANTVNINOc AvG) laureate bust right. 

Reverse: ΝΙΚΑΙΕΩΝ  (NIKAIEwN) (NIKAIEVN) Hexstyle temple with peaked roof. Pellet in pediment.  The diameter is 23 mm and is 4.92 g, die axis 90 deg.  Reference: Recgen 566? (reverse of Caracalla, but legend of Elagabalus), Not in BMC XIII (Bithynia).  It matches Roman Provincial Coins Online Examples without reference # listed.  566 has different legend on Roman Provincial Coins Online, but 566 might be the closest. RPC VI, 10814
