There was never a dime popularly called a "war dime". That term was usually applied only to those coins whose metal composition was changed due to wartime metal shortages - e.g. cents in the US and nickels in the US and Canada. Because dimes were mostly silver their composition wasn't changed, so regardless of date they're just dimes.
