This has been covered before. It seems to be a recurring topic every few months. For self-preservation, it is wise to be a bit paranoid. We are all involved in a hobby that entails cash (coin). Some on larger scales than others. It would be wise to ensure that there are no traces of the hobby around our personal residences. No one wants to invite harm to ourselves and our loved ones. Everyday in this country, people face tragedy for lesser amounts. That being said, it would also be wise to change up any routine that you might have.
To answer the question, the public trash bins are used. Sometimes it is a gas station, sometimes the grocery store, McDonald's, etc. Spread it out. Don't leave it at one place. In addition, you might want to double bag the trash. Employees at these places are paid minimally and if they decide they need a raise based on the $6000 in coin wrappers, they might end up following someone home.
Stay safe everyone and happy hunting.
