#PL111 - Group of 6 Different Richard Nixon Presidential Campaign Buttons You get all six different for $5. Vintage unused buttons from the 1968 and 1972 campaigns. They are in very good shape. Richard Nixon has always been popular with collectors and this is a good price on these as they are getting harder to find with each passing year. Average size is about 1" diameter. It's unlikely that we will ever be able to offer them at this price again. $5.00
