Try a magnet to see if it sticks, then look at the 3. As was stated, the 3 in 1913 and the 3 in 1943 are completely different. Based on the 3s alone, what you have there is a very grungy 1913 cent, but I do see where you could see the 4 in the picture you uploaded with your loupe. Nevertheless, its a 1913
If you have a reprocessed 1943 handy, which would have a good clear date, COMPARE the 3 to the OP's coin...
