I'm in NVa...and TD Banks are best when it comes to dumping! Because there are many MANY other persons doing precisely the same thing I'm doing, these machines are in constant use. There are also an extremely heavy number of immigrants and foreign students/diplomats in my area and usually some foreign coins (and STEEL cents) in the removable magnet located in the 'cage' device used to filter the coins streaming from above into the counter's hopper. This cage is inserted into a hole cut for it in the big wooden case covering the counting machine. I 'turn on the charm' and ask to take a look and the teller will allow me to remove the magnet from the cage - and usually I'm granted not only a look but rights to the whole shooting match! I've collected coins from roughly 40 to 60 countries this way these past 4 years and as long as I can keep changing my operating procedure, I'm looking forward to several more.
