EF-45 is often called "Choice Extremely Fine" to distinguish it from EF-40. Specifically,A coin graded EF-40 may have a slight amount of wear overall, but its features are otherwise sharply defined. Traces of mint lustre may still be visible.A coin graded EF-45 has light wear only on its high spots, and all details are very sharp. Mint lustre is readily visible on significant parts of the coin.Source: United States Mint
