NIKE Stirling Silver 1980s Promotional Ring Sz 9,12grams

Vintage Nike Stirling Silver Men's Signet Ring Size 9 and weighing a very Chunky 12 grams with jewellery grade black enamel inlay featuring the Nike logo, the ring will need a polishing for scratches and the .925 stamp is barely visible only seeing the "25" but I have tested it multiple ways and all test come back positive for stirling silver, I've had this ring for almost 35 years, I rarely wore it because it feels to heavy for my liking, and it has followed me everywhere I've lived, I wasn't gentle with it at all so that obviously reflects in the cheaper price I am selling it for, as always I will consider all offers and I am open to trades for full change jars, old coins, old military items and toys, I can ship for around $10 in Canada and the U.S, otherwise pick up in Port Hope, thanks for looking!
