I have a number of ancient coins that I know nothing about. I would be grateful for info about them, tips on conservation, etc. Thank you for your time! This is 16mm. I can get you a weight if you need, but hopefully the images are good enough.
Constantine I A.D. 335 CONSTANTI-NVS MAX AVG; rosette-diademed, draped and cuirassed bust right. GLOR-IA EXERC-ITVS; Two soldiers helmeted, stg. facing one another, reversed spear in outer hands, inner hands on shields resting on the ground; between them two standards. in ex. •CONSA• RIC VII Constantinople 80
Thank you! Time to research this. Should I be doing anything to conserve this coin, or leave it as is?
