Since most of your coins aren't from Canada, I've moved this thread to the World Coins section.

Here's what you've got. I have a 2006 Krause, which is a bit out of date by now, I'm adding a little to the value stated here, but in some cases I may not be adding enough.
#1: Canada 5 cents 1870. There are two varieties listed, "flat rim": and "wire rim", but yours is so worn down it's got not much rim left at all. I'd call it Good at best, and the catalogue only goes down to Very Good. I'd guess it's a $5 coin at most.
#2: Cuba 1 centavo 1916. There is a massive price jump between EF ($2) and Unc ($50); I think your coin is somewhere in between those two grades. I'd guess a $10 coin?
#3: France 5 centimes 1915. These coins always look weakly struck; it's hard to determine a grade for them. I'm going to guess VF. $1.50.
#4: France 5 centimes 1913 (it's not 1918; they didn't make these coins in 1918). This one's got three huge punch marks right in the middle of the obverse, which travel all the way through to make "lumps" on the reverse. That'll kill any numismatic value this coin might have had. It's scrap metal value - a few cents.
#5: Great Britain florin 1918. This coin is made of sterling silver (.925 fine), so my catalogue values will be way off the mark. .3364 ounces ASW, $5.45 at current silver prices. I'd grade it an American Fine (British VG - the Brits have much stricter grading standards than you do in the US) - that should give it a premium of a few dollars above spot - call it an $8 to $10 coin.
