Volunteer plants?

This year we used the compost soil that we collected all year last year. We would throw in old veggies, organic matter, and soil, then churn up the mix every so often.
After planting a bunch of our tomato plants in the compost soil, we have ended up with hundreds of "unknown babies".
we are assuming most are tomato plants of some sort, with a few gourds and squash thrown in there too.
We have transplanted a good many of them into their own 4 packs.
Has anyone else ended up with this?
would any one be interested in these plants for your gardens? the mystery would be fun in my opinion.
Has anyone has success with these volunteer plants producing well?
thoughts?
