Each is 3.5". For each we will give the Hake number as well as the Hake 2004 Revised Prices value. First at upper left accented by red and blue elephants is Hake #8 with $85.00 value. Second at upper right by Gogerty is Hake #2008 at $85.00. These first two are extremely clean although this second one has small raised bump above Nixon's head caused by the reverse bar pin. Third at bottom reading "Pull 1st Lever" is Hake #2019 at $102.00. This has some long but light hairline scratches over the Eisenhower portrait although these show only in reflected light and the button displays totally clean.
