Hufflepuff's Cup

[Jamie]

No: HPFGUIDX 138717

    I searched for a while and didn't find any threads on where the cup 
may be hidden, and apologize if I missed it.  So, what do you think?  A 
bit of a longshot, but could it be the goblet of fire?  We know the cup 
has unknown magical properties.  We also know it's beautiful and the 
goblet is not, but wouldn't it make sense for LV to transfigure it 
before placing it under DD's nose?  It's quite possible that the goblet 
remained in its casket a long time before the triwizard tournament, so 
DD may not have known what it looked like.
