Catalytic converters prices?

Hey all, not sure if this is where I could ask this question... so sorry if this isn't the place. I've been cleaning up my brother in laws Mercedes shop (selling excess parts) and he had been just giving away all his metal and batteries until I stepped in and decided that i'll scrap it all and we can split the money we get. He has about 8 catalytic converters that I want to sell but not really sure what the going price is or how the price of a scrap catalytic converter is given. If anyone can help me out with this it would be great, i'll add some pics to show the items. Thanks, Hector.

just realized I cant post links due to being a new account, if anyone knows the answer to my question just pm me and i will pm you imgur link to see what I have and how much they would go for. Thanks!

Where in the USA are you located?

We've had quite a bit of discussion on this, you might be able to use the site here for reference only, you know prices/pic's.
I'm not promoting them, know nothing about them. Find a couple of different places like this and compare their prices.
At least you'll know what to expect price wise and compare to your local yards, if it's too low then ship them.
Also look down at the bottom of your thread here and there is other pertinent posts about them.
