I used to go to my local Coin Store, (VP Coins) and stand at the counter for a couple hours at a time and pick out any coins from the 'foreign' box that did not look familiar to me. I also found quite a few error coins this way.  
Price was 6 coins for $1. If I could have just bought 1 or 2kg for a set price, I would have, but he didn't sell them that way.  I mostly came home with 50-60 coins. 
I haven't done it for some years, and standing like that would wreck my poor ole legs now.
