The foreign coins are probably demonetized. You can pick them up for 3 or 4 for $1.00 at flea markets. The other US coins are all normal. All are worth face value except maybe the Buffalo Nickel. Could be worth $1.00 or $2.00
That depends on what you mean by "good." The Canadian quarter is silver. The wheat penny is worth 2-3 cents. The buffalo nickel is worth around a dollar. The Canadian Toonie is worth $2 in Canada. The rest are just common American or foreign change.
The Buffalo Nickel is the best of the lot, followed by the Wheat Ear Cent. Spend the rest snd welcome to CT.
I think that they are all current now, actually. The only one I am not sure of is the Swiss coin, but since they don't use the Euro, it is likely good. The Euro and Canadian should be spendable at face (but dont spend the silver quarter!).
The good thing is that you're asking for advice which means you're at the very least semi interested. The great thing is that you have something to build on if you're interested in collecting. It all starts somewhere and which one of these coins interests you the most?
Silver certificates in that condition are probably only worth face value. I've heard that some coin shops give them in change. Bicentennial quarters are common. I regularly have more than one in my quarter jar. The cent looks like roadkill - copper plated zinc that's had the copper scraped off. Sorry, all spendable.
My LCS sells silver certificates in that condition for a few dollars. I would keep it just because I can. As for the Quarter, it looks to be in good shape but they made so many of them it’s only worth face value. Keep if you like. The cent, spend it.
