Thank you both for the links to these great coins.
Sooo ... I am trying to convince myself that my next pursuit is a search for all 13 Oregon Trail Halves by Date/MM ...
Great fun can be had pursuing this complete set of IMHO the "best" coin of the classic silver series ... my personal bias is that I truly enjoy this coin design.
I've been doing my homework ... found a price I can afford for each coin ... and will apply the same standards that I have always used ... exceptional coins only need apply for the set. PCGS
MS66 minimum ... white or nearly so ... well struck ... and CAC approved.
Currently have two MS Oregon Trail halves in my collection ...
1936-S ... PCGS
MS67 ... but CAC rejected.
Great coin IMHO ... photo ...
And the current coin in my Type Set ... 1938-D PCGS
I'm wavering on this mini-set of great coins ... should I pursue or not ... current thinking is yes.
