E121 back variations and scarcity
 

I remember a thread a while back talking about this subject but couldn't locate it. My question is about rarity of the 4 different back types of E121 cards. Type 1 ends in the words " of the". Type 2 ends in the word "eighty", type 3 ends in "of the" and has serif lettering instead of block lettering, and type 4 is a reverse print type.in order of scarcity, how do these backs rank?

Thanks,

Ken

Is this the thread?
