The picture shows a view of all (4) Old Metal Scottish Terrier or Scottie Dog Jewelry Pins in this lot. These Scottie dog pins are not dated and the year that they were made is unknown. They are not marked and the maker is unknown as well. The backs are blank. They are believed to be made of brass and the black one is enameled. The two larger ones are a matching set. Each of these have a pin with a clasp on the back. All four of these for one price! To judge the sizes the largest two pins each measure 1-3/8'' wide. These appear to be in near mint to mint condition as pictured.
