Smallest is 5/8" and largest is 1" oval. First item names New Jersey Women's group, second names "Conn Coolidge Club", third and fourth are each variations on the slogan "Courage/Confidence" with the first of these including the word "Duty" along with the name "Dawes." The button inscribed "Cal" is the first we've seen but we doubt its relationship to Coolidge. It has a tanned back paper by Westminster Press, more known for Sunday school supplies than political buttons. The last two buttons are from 1926 Pennsylvania election rather than his 1924 campaign year. Both of these include the phrase "Vote It Straight." One also adds "Support The President." Tiniest age trace on the "Cal" button but all others are Exc. to Mint.
