A lot of lures and fishing gear are not worth the package they came in, but these seem like good quality lures.
They are in the 14 to 20 dollar range which make them collectibles more than used to catch fish.
My preference is live bait, but it's not easy to catch on demand. It's an opportunist thing. Salmon fishing is like that too, some days they like one thing and something different on another. A good fisherman is able to change it up regularly and find what works best, but a well stocked tackle box is a significant investment, even without buying designer lures.
I wouldn't use them for trolling because they are too easy to lose. Guides wouldn't use them because they are too expensive.
The bleeding eye looks like a really nice lure though. I have fishing spots where we anchor the boat over smooth bottom and unless the line, gear or knot breaks we rarely lose gear. I've got some jigs that I've been using for years. Sometimes I repaint them or re-apply color shift tape when they get beat up. Abalone shell adds nice weight and natural color shift and I'd
bet these lures are effective.
Trolling spoons are popular here and mussel shells are the perfect shape to cut them. We'll know for sure next summer.
