Possible Horcrux

Have been lurking a bit now and have a thought of a possible horcrux.

Dumbledore says that Voldemort uses things that are significant to him 
or trophies.  Well, he has a trophy in the school--his award for 
special services.  

As we don't the actual process of creating horcrux, this is 
speculation, but what if when he came back to the school to apply for 
the DADA job, he turned his trophy into a horcrux.  It seems something 
Voldemort would get a kick out of, having one hidden right under 
Dumbledore's nose.
