It makes me sad that you would remove it instead of repairing it. Old craftsmanship is so beautiful, and removing it would remove a little bit of beauty from your home. If you are planning to duplicate the floor that is one thing, but I'm sure that would cost a fortune.
I'd have a floor person evaluate the damage. I had a similar problem, and they cut the toungues off of the boards, built a new piece and put it in. One area needed to be feathered to blend in but you can't even tell where it was done.
there is a reason that I have never even considered buying a home younger than 75 years - you can't begin to compare the "personality" of an old house with a new house. My (hopefully) new home is 140 years old, sure it has some problems (like 140 year old windows!) but there is a reason it has stood for that long. I know of more than one $300,000 new home that is only a few years old that has structural problems already. Those homes aren't going to make it 140 years, plywood and drywall doesn't hold a candle to solid wood and plaster!
If you are getting ready to sell, you will have buyers who want an old house, with old details. That will add value, not detract. My current home has 1 inch quarter sawn top nailed floor boards (a Rochester floor) it's beat up and shows all 75 years of it's life, but the house wouldn't be the same with a new floor.
