Coin Sinkers are lead weights used in fishing to sink the bait or lure to the desired depth. The sinkers come in various sizes and shapes and are attached to the fishing line. Coin Sinkers are typically flat and circular in shape, with a small groove around the edge where the line is attached. These sinkers are called "coin" sinkers because they are generally about the same size and shape as a coin.
 
Coin Sinkers can be used in both freshwater and saltwater fishing and are especially useful when fishing in deep water or fast-moving currents where the bait or lure needs to sink quickly. These sinkers can help control the depth at which the bait or lure is presented, allowing the angler to target specific fish species.
