British Honduras (now Belize)... not to be confused with plain old (Spanish) "Honduras". Although, to be fair, "old Honduran silver coins in better grades can be quite pricey" could be correctly said regarding either.
As for Brit. Honduras, earlier pieces (aka King George V and back), in higher grades do indeed jump in value.
If we're talking just a pile of old change, Elizabeth and George VI... maybe an 1894 dime or 1916 cent that are really worn - that's pretty much junk.
Maybe pull out any Geo. V that doesn't look too heavily worn, post a few decent pics of the group, and we'll get an idea what's what.
