1864 Guernsey 4 doubles with medal turn alignment

Does anyone have any information about the 1864 Guernsey 4 doubles coin with a medal turn alignment?  I saw that there was a variety (KM #6) but I didn't see anything about an alignment variety.

 

Thanks much in advance for the help.

The 1864 has both coin and medal alignment:

I also found that the 1864 has an overstrike (1854)
