I am writing an art paper and need to know how to write a citation for a coin I found off artstor.org

This is how they display the information on their site:
Title Silver Coin of Nero: obverse and reverse
Description From mint of Antioch
Subject Nero, Emperor of Rome, 37-68

Sculpture:Coins--Roman: Julio-Claudian--27 B.C-69 A.D
ARTstor Collection ARTstor Slide Gallery
Source Data from: University of California, San Diego
Download Size 1024,1024



I will need bibliography and in-text citation.
THANK YOU!
