Old School jewelry

" I made a ton of cash off of my old school jewelry."

I just had to laugh when I saw that on an infomercial for some 800 number for a gold buying service. I didn't know there was such a thing as old school jewelry; especially some that you can make a ton of cash from if you call an 800 number. I'm going to go get me some old school jewelry and call that number and see if I can make a ton of cash too. Maybe I'll get to be in an informercial too or at least have some paid actor portrayal.
