You're getting confused. The two obverses for 1920 are : 1. the common regular issue, as from 1913 - 1921 (all but one or two 1920s are this) 2. the shallow head design (Freeman 189), which you can see on half the 1921s, all the 1922s and the non-ME 1926s. It's akin to the 'recut obverse' used on the larger silver from 1920-1926, and yes, it does have different pointings, but many other differences such as overall size of the bust, style of lettering (serifs), shallow 'flat' look of portrait, etc. Needless to say, yours is NOT that one!
