Awesome info, @packyman! Thanks for sharing.
Out of curiosity, does the English ©1999-2000 unlimited edition print run have a difference with both of these as well? I once mentioned this for determining the Base Set Energy language:
Thanks to you, the Korean and Chinese ones now can be distinguished from one another for the 1st edition ©1999-2000 Energy cards, but I was wondering if they can also somehow be distinguished (visually like that) from the English ©1999-2000 unlimited edition print run. 
Oh, and thanks for ‘sacrificing’ the booster pack and deck you’ve pulled these Energies from, in case you did so recently or on purpose. 
Greetz,
