Does anyone know where to buy those magnets that catch your pocket change?
I understand that u.s coins are non magnetic. However, I live in Canada and i’ve definitely seen people use them before when i used to be a cashier. The only picture i found resembling what i’m looking for is here – http://lumberjocks.com/projects/22615 . Canadian coins are magnetic

They’re just neodymium magnets (rare earth magnets) that have been put into a nice wooden case. You can pick up the magnets on ebay for a reasonable price, and I’m sure you could either buy or build a case.
Hope this helps, Daniel.
