Vintage 10K Gold 25 and 30 year service pins together. For Sale

Vintage 10K Gold 25 and 30 year service pins. I have searched repeatedly with no definitive answers for the Company that gave these service pins to their employees. More than likely they were made by one of the major North East manufactures that provided these types of items. They are in very good condition and I'm sure have a collector or sentimental value for someone because they are 10K gold and not plated, a rarity today. Shipping is included. Thank You for looking.
