I have a couple of medium grade guns; an L C Smith 3E and a Fox A grade. Both guns are tight on face with good barrels etc.. Both guns have been handled a lot during their 100 year lives and I expect experienced some sanding although both still have wood slightly proud or flush with the metal. As a result the checkering is just about gone on both of them. The wood grain and tone is pleasing to my eye. I have contemplated having them recheckered. . So if they were yours would you have the wood recheckered or just let them remain with their now near smooth wood? I don't contemplate selling them.
