First thought, didn't check it:

DuplicateHandle(...) presumably will fail on invalid handle.
If not not, then you can try DuplicateHandle(...) and call CloseHandle(...) on the result. CloseHandle tends to through exception on closing invalid handles ( no exception for NULL though, but it's easy to check; and no exception on pseudohandles, like GetCurrentThread(...) result).
