In the many years I have spent collecting I found hanging around the old timers shops I acquired a font off knowledge and made some great friends. I love to dive in the dumpsters around my complex because of the treasures that through negligence or just no interest. I buy double eagles just to feel in my pocket. The feel of a precious metal coin in my hands is awesome.
Anyway, I learned that cleaning a coin other than wiping hand oil off is discouraged and hurts their value. I don't listen some times just because I love the look and feel of the precious metal in my hands. Also I want to do my part cause other coins to appreciate in value.
I also love breaking sets. Oh, plastic cases and celllo fitted holders allow them to be handled without damaging them. Like collector cards its all about how they are stored and handled. Get kids started with plastic cases that keep finger prints and oils, accidentally dropping or just plain air and Light.
Stamps and jewelry follow suit as do my guitars and fine wood instruments.
You have something seriously wrong with you. 
You destroy the value when you clean coins AND when you break open sets. To most collectors, it is a terrible idea.
