Hi Ethem, is this an Italia (Italy) 20 centesimi coin? World coin pictures may be found here: http://worldcoingallery.com/index.htm , http://www.coinarchives.com/ , and http://www.numismaster.com/ta/numis.jsp . If it is, collector value may be worth about .20 with heavy wear to around $2 with moderate wear to maybe $6 with light wear to perhaps $60 with no wear (uncirculated). There were 13.67 million minted that year made of nickel. You might also try a library for a copy of the Standard Catalog of World Coins for pictures, values and lots more interesting info.
