Two Monet necklaces - vintage!

Vintage jewelry cache -- an older relative cleaned out her jewelry box for downsizing prior to a move, and here it all is! Two silver costume jewelry necklaces from Monet. First one is three chains together, with a hook and eye closure adjustable between 15" and 16.5" in length. Second one is a made of open links with a hook and eye closure adjustable between 14" and 17" in length. Why not sell them individually? The shipping cost makes it not worth it, for buyer or seller. Definite 1980s vibe with these pieces!
