Because it is causing a Checkwiki error #73: "ISBN-13 with wrong checksum", I removed the ISBN from the citation

V.P.Alexeev, P.G.Loboda "Electrum Coins of the Greek World Found in Nikonion, Berezan and Olbia". Ancient Black Sea Area. Issue IX, 2011, pp. 22–29. Odessa : "Fridman A.S.", p. 520. Texts in Russian. ISBN 978-966-96181-5-1 Parameter error in {{ISBN}}: checksum.

This citation has other problems:

• If the source is a journal, provide the ISSN of the journal using {{ISSN}} rather than an ISBN;

• If the title of the journal is Ukrainian, do not translate it. I could not find a journal entitled Ancient Black Sea Area on the Internet;

• Titles of journals should be italicized. See Wikipedia:Manual of Style/Titles#Italics
