Collection of mid-20th-century style political campaign buttons

A group of four circular celluloid or tin-litho pin-back buttons, stylistically consistent with American political campaigns of the 1960s. The buttons vary in size and color: one orange button reads 'BILL BUCKLEY FOR MAYOR' in black block text; a small dark blue button features 'nixon' in lowercase red text; a larger white button displays 'NIXON AGNEW' in stacked red and blue capital letters; and a fourth red, white, and blue button reads 'ROCKY A Great Team WILSON'. The items appear to be made of printed paper or metal under a clear protective layer, typical of vintage campaign ephemera. Minor condition issues are visible, including surface scratching, slight scuffing on the white button, and minor oxidation visible on the metal pin stems protruding from the top two items. While the text on these buttons refers to historical figures like Richard Nixon and Nelson Rockefeller, they are identified here as stylistically consistent with that era (roughly 1965-1970) rather than verified originals. Authentication by an expert would be required to rule out modern reproductions or more recent commemorative strikes, as there are no visible maker's marks or manufacturing stamps from firms such as Green Duck or AO Co. in the provided image.

Based on my visual examination of the four political buttons, they appear to be stylistically consistent with American campaign ephemera from the late 1960s. I am evaluating these under the hypothesis that they are period pieces representing the campaigns of William F. Buckley, Richard Nixon, Spiro Agnew, and Nelson Rockefeller. I cannot verify from a photo whether these are period-produced items or modern commemorative strikes, as they lack visible maker's marks from known manufacturers like Green Duck Co. Surface scratching and oxidation on the pin stems suggest some age-related wear, though a physical inspection would be required to rule out artificial distressing. The market for mid-century political memorabilia remains steady, with items associated with prominent figures and unique mayoral runs like Buckley's often attracting collector interest. The estimated value of $45-$85 reflects the group as period pieces; should they be identified as modern reproductions upon physical inspection, the value would likely drop below $10. To establish a more precise value, an in-person examination by a specialist in political history would be necessary to verify the lithography techniques and material composition against known period standards.
