Well, you did OK. Without researching them and despite their wear and minimal value, you certainly got more than your $20 worth in the U.S. and Canadian lots...don't know how much more, nor the other foreigns of which I know nothing about.
You did OK. The Columbian half is the big ticket item worth close to $10 just in silver and since it was the 1st commemorative half I'll call it $15, the 57 dime is about $2, the 06 nickel is $1. I'd give a buck or two for the Canadian nickel, the Brazil 10 centavos piece is maybe 25 cents. So all in all not bad.
