I can just make out the camel on the reverse of the Trajan denarius - pretty cool! I missed it at first glance.
Beautiful! I have a different issue with a similar reverse type: Trajan, AD 98-117. Roman AR denarius, 3.35 g, 18.3 mm, 7 h. Rome, AD 103-111. Obv: IMP TRAIANO AVG GER DAC P M TR P, laureate bust, right, with drapery on left shoulder. Rev: COS V P P S P Q R OPTIMO PRINC, Arabia, draped, standing left, holding branch in right hand over camel walking left before her and a bundle of canes (?) in left hand.
