OEM Catalytic scrap value? And how to get best price?

[senor perfecto]

What should I expect to get for a (non functioning) OEM cat from my 2002? Will the mechanic who installs my new cat just buy it from me for a fair price, or should I take it to a local scrap yard to sell?

Local scrap yard and not an automotive scrap yard, but general scrap yard.
