Oregon Commem And Buying Cleaned Coins

Ok, I put the Lithuanian's coin next to one from PCGS coin facts (MS67+). Now although the grades are way different, I do notice something odd in the tail of the number 2. The edge of the bottom line seems to extend farther to the right in the PCGS coin than in the Lithuanian's. I think I see what moxking is referring to here as well (i.e., fatter font on the date numbers), but wouldn't one expect that due to wear (i.e., flattening out of lettering)?

one_fine_dime - you already did what I would have suggested, which was to place the fake next to a known authentic example. Since the fake photos are so unclear I can't pick out the most common tell on cast counterfeits, which are raised dots or marks above the fields (most commonly). This happens during the relief process from the original coin.

Everything is thicker on a cast counterfeit, not just the dates or words, but the dates or words are usually the easiest to detect as enlarged. Note any detail and your comparison will show the 'fatness' of everything which also "squishes out" those small details.

Oregon Trail coins are a wonderful testimony to the great artistic couple of James and Laura Fraser. Caution must be utilized as the various date/mint combinations possess enough differences between them to cause confusion in expectations and therefore grading either numeric or subjective.
For luster and superb toning, it is difficult to beat the 1926-s.
For duller and somewhat lifeless surfaces, the 1939-P comes to mind first with the 1938-P often the least attractive of the 1938-PDS set. Of course, like every rule, there are exceptions but I think it's generally as I've indicated.
The plethora of original packaging has contributed to abuse at the hands of the uninformed and cleaned or lightly circulated coins are rampant. Sulfur can be a great toning agent or the angel of death depending on the thickness of silver sulfoxide and the coin's surface type.
