Everyone has had the same reaction as i have had. The obverse looks prooflike to me but the reverse looks like a biz strike. There were cases where after a proof run, the dies were used for business strikes as well. I'm not sure it happened in 1939 but this coin sure looks like that may be the case.

The reverse looks like a buss strike.
