1849 $10 Oregon Exchange Co. Ten Dollar XF40 PCGS. K-2, High R.6. Production of Ten Dollar gold coins by the Oregon Exchange Company started after the first Five Dollar pieces reached circulation. Engraved by Victor M. Wallace, the dies omitted the errors of their Five Dollar predecessors by changing T. O. to O. T. (for Oregon Territory) and correcting John Gill Campbell's initial from G to C at the upper obverse border. Interestingly, the initials for George Abernathy and William H. Wilson were removed because, despite their status as co-founders of the Oregon Exchange Company, they did not provide any of the money required to purchase the coinage equipment.
