This was in the house 60 years ago. I believe it's black lip shell, possibly pearl, but it's unconfirmed. It's quite old, but relatively clean. Only the silver clip-on tie pin has no maker's mark and is unknown. This has more damage than the others. The pin on the black lip shell tie pin is bent. (It can be inserted, but it's difficult to remove and insert smoothly) Please understand the above points before purchasing. <Additional Note> There were no maker's marks on the pearl and black lip shell tie pins. However, as they were stored together, I believe they are from the same maker.
