Sounds about right.
Not many foreign coins worth a lot.
Might get a little more, but not much.
I bought a bunch of the Mexican 5 and 10 cent coins with the Aztec calendar on the back.
1936-40 ish..
Not worth very much. Depends on the buyer.
I think they would be fairly hard to spend here in the USA. Not much collector value there either, so, unless you plan on going to each country (and also assuming they're still valid coinage) they're virtually worthless.
