spottin dimes 

A display of using very good vision.

Jerry : how could you see that from all the way over there?
George : I was spottin dimes.

Eating onions and spotting dimes 

Seinfeld reference. When George can spot dimes from a distance but mistakes an onion for an apple when not wearing his glasses. Used when things don't make sense.

You're eating onions and spotting dimes, I dont know what's going on. Its total chaos.
