Congratulations CoinsKelly.

You are now holding in your hands an honest example of what my personal aesthetic considers to be the finest example of coinage art in the entire classic silver commemorative series.
The Fraser/Fraser team created for us an evocative image that to this day resonates through the Oregon Trail Half Dollar.
In case we forgot ... Laura designed the "Indian" and James designed the "Conestoga Wagon" ... there is still somewhat of a debate about which side is obverse versus reverse ... I give Laura the credit for the obverse with her tremendous Indian chief holding back the flood of settlers.
I recall as well your long and diligent search for an example that meets your collecting needs ... as such I am truly happy that you finally found
your coin.

A technical evaluation of your Oregon Trail seems somewhat out of place ... the nature of your long standing search for an example that pleases you should be cause for celebration amongst us commemorative fans.

That said ... since you asked for it

... in my view your coin has a technical grade of XF45 (details) ...
The circulation wear evident on your coin is certainly below an AU grade based on my experience with worn examples of the series.
To the best of my judgment this coin ... lovely as it is ... would not certify at a
TPG ... issues being the rim cuts and the gouge in the pack animal on James reverse ... hence the 'details' opinion.
Back to real world of satisfied collectors finally achieving a goal ... I am thrilled for you CoinsKelly that you are finally holding this coin in your hands.
Looking forward to anything else you might someday share in our small world of commemorative coins.
