Worth keeping or selling old CAT?

[ElGato]

I replaced my catalytic converter unit with an aftermarket (non-OEM) one a few weeks ago. Now I have the old cat, and would like to know what you think I should do with it. I think it's leaky, but it doesn't rattle and seems intact. ~94K miles, never removed before now. Pic below:

For the value of the car, in terms of collectability/completeness, should I keep it? I'm working to keep the car as original as possible, but I couldn't justify $2K+ for an OEM cat. Again, it may be leaky somewhere along the seams.
Or should I sell it? What's it worth? Honest estimates, please, if it's worth anything. Local pickup in Gilroy, CA. This is not a For Sale posting; I'll make a separate post if I feel like it. Thanks.

if it's was leaky and happened not to be in a repairable condition, the metal alone is worth at least $150 +

I scrapped two old bmw cats I had laying around and got $380. Not worth selling it, the shipping hassle is just annoying, I'd scrap it and move on.
