Note the die state of this coin for the obverse? That is the clue. No die wear on this coin. The OP's coin shows die flow towards the rim. So whoever created this die, made it with a later die state coin and not a EDS example.
Busted The reverses could be used dies, but the obverse for these 1943 copper and the 1944 steel cents should have a EDS fresh die for the obverses as they are the first coins struck with them.
