1944 is a common date for Mercury dimes and there are no significant varieties.
A 1943 dime made of mercury is not rare. It is actually an error coin as dimes were made of silver that year. An authentic 1943 mercury dime would be valuable due to the mistake in using the wrong metal. You should consult with a professional coin collector or numismatist to authenticate the coin's rarity and value.
If it's a U.S. dime with a date of 1944, it's a Mercury dime.
