Ever Thought Of Coin Shops Salting The Coin Supply?

there are better ways to get people interested in coin collecting than putting special coins in rolls for people to find. Like have a press conference saying you spent a special coin or coins at a convenient store so everyone in the area will look for them in their change, and even tell them how much the coins are worth. This has been done a few times like this by big dealers and that seems allot better way to get "people interested" in collecting. Most roll hunters are hoarders not collectors so I believe that would be like shooting themselves in the foot
