Click here to see Makinen lures sold recently on ebay. It's not overly popular, apparently.
I used to collect old lures, and got $600 for one once that cost me nothing. If you find anything Heddon in original boxes, you might have something worth a lot. Same goes for anything Creek Chub and wood, Punkinseeds and wooden jitterbugs... there are rabid collectors of those out there.
