Pollock delisted this in gold. Judd apparently listed this because of the silver trials listed below. We list it here because it is clearly something beyond a regular issue.
Recent research by John Dannreuther has determined that these J34-J34A/P46-P47 are true die trials made in 1834 from old dies and were struck prior to the gold issues. The obverse die was an unfinished die with "180" already punched into the die, the "4" being added from a modern punch. The die was lapped to remove rust. The reverse die appears to be an unused 1806 half dollar die. For more information, collectors should read the August 14, 2006 and November 24, 2014 editions of Coin World.
These were also struck in silver with reeded edge J34-J34A/P46-P47 with the dies is a slightly earlier state than the gold examples proving that these are true die trials made in 1834 prior to the gold strikings. Only 4 or 5 are known. There is also a single example known struck with a plain edge J34A/P47. It would be interesting to see if this was the first one struck.
