Value of stock converter?

[nsmall]

I can share pictures tomorrow but I have a 1973 727 with a stock torque converter that worked fine but I swapped out the stock torque converter with a new one so I was curious what the stock one would be worth....any advice?    $100?

Thanks

Maybe I'm wrong and it's not even stock but here's some photos of what was in there....

As a rule I never buy used converters , you never know what is in them as far as debris from the trans .
But in your case I know it is clean & working well . no advice on price but take what you can get !
