There are 2 versions of this coin. one was using the 1922 die type and the second was the 1944 die type.
This link is the older 1922 die

This link is the newer 1944 die

easy way to tell is to look at the mint marks
Notice by the bottom of the crest on either side there are marks, they are different on the 1922 version and the 1944 version.
Both coins are 1944. the first link with the '22 dies have the mintage for the entire 1944 run. my assumption is that its rarer if its the KM# 161.1
