Considering that the PCGS#'s of these two coins are so far apart, I have to wonder if there was a change in the numbering system and/or variety designations, and if that has something to do with the missing data. Beyond that, no idea.

The pop numbers for your coins above return errors, so the numbers must have changed as MrEureka suggested

 
There is also no mention of the "High Relief" variety in any of the pop reports.
