Donate oil lease inheritance

Our mother passed recently. I, along with my 3 siblings, inherited her oil leases. If I remember correctly, there is a cost to transfer these leases if we were to keep them. Because of this, to split them amongst the 4 of us doesn’t make financial sense. We are considering donating them to a local college where my father taught. If anyone has done this I would be interested in hearing how you did this. Would there be a cost to the college? Will they pay for it because they will own the leases in perpetuity? This would occur in Illinois.
