Welcome. Steve, mintage numbers and rarity are key to value in coin collecting. In this case 62 million 1944-D were minted, hence not at all rare. This coin might be in the VF range, so 20-35 on the grading scale but the surfaces look pitted to me, which would lead to a "details" grade. IMO, this dime is worth about $2.50. Definitely not worth grading.
