Tetradrachm from Athens, Greece, circa late 5th century B.C
The obverse has the head of Athena and the reverse an owl with an olive sprig. There is a test cut on the reverse between the legs of the owl. This makes the coin fairly easy to identify.
While reading a book titled " Abe Kosoff Remembers" (It is a compilation of the columns written by Kosoff for Coin World between April of 1967 and June of 1980), I came across a column with photos of an Athenian tetradrachm with a test cut. The column appeared in the November 8, 1967 issue and centered on Athena.
Somehow the coin that I purchased in 1984, had been photographed much earlier and was selected for use in 1967.
I don't know who owned it previously, but I'm glad that someone found it important enough to photograph.
