Once you get over the penny habit, start looking for silver.



Yes you can find plenty of silver in the scrap pile, I use the back end of a claw hammer to strip the screws loose from the back panels of electric ranges, washing machine, dryers and electric hot water tanks. What your after is the rheostats inside each one has small silver contacts.
Since the rheostats are made from Bakelite you can smash them open with the same hammer you used to strip the screws off the back panels.

Circuit breakers from old electrical panels, magnetic start switches the bigger the better all have silver contacts inside, the copper bolt below came from a large Delco Remy starter from inside the solenoid.

Stop messing with pennies your not even making gas money.
