Got these shelves in our walk in pantry and getting a cabinet maker to install cabinets instead
To save some cash I'll take off all the existing shelves. Assumed these were screwed but I was wrong. They are all nailed in with a nail gun and the nails are recessed in

I don't want to damage the walls prying out the supports if I can avoid it
I was thinking of using a small hole saw to drill out holes around each nail and then pulling the nails out with pliers
Unless someone has a better idea?
