I removed some trim boards and I used the technique of pulling the nail through the wood to avoid splintering the finished face (instead of pounding the nails back out).
This resulted in the heads of the nails enlarging the holes slightly.
Since the oak is old, it is as hard as cast iron. Driving nails into it results in bent nails. I could predrill holes but that is extra work!
Are there any tricks to reuse the existing holes?
