Coins with face value "20" - identifier

This page can be used to determine the issuing country of an unknown "20" coin whose inscription you cannot read.
Simply compare your coin to the images available here.
Only coins from the 20th century are shown here, and only those with the denomination written in regular Arabic numerals (or rather, what we used to call Arabic numerals).
Pictures are clickable - by link you can go to the section of the catalog with coins of this country and see detailed information about the coin you are interested in.
If your coin does not have such numbers on it, try to identify it using the "Coin Identification" section.
