In some of my books to mark them as mine, I will mark them. Usually on my kids birthday s. I will go to page 422 for example and on the page find the initials of my kids and add the middle letter. So if a sentence ends in a d and next sentence starts with a b I will put a small c in the middle. Now most of these are higher end books that have never been read. Also don't ever plan on selling them. But if I did I highly doubt the buyer would ever read it. The only way I can see someone seeing it is if they actually read the book and when they got to that certain page see it. So my question is kind of like if a tree falls in the woods and no one around does it make a sound. Same thing here in principle. Does it hurt value when no one even knows it's there and has been marked. I think this is very different from say the person's name on the front page. Or someone writing n inscription like happy birthday or from the library of so and so. The reason I do it is so when my kids get these they can look at there birthday and see it marked and remember good Ole dad. Also thomas Jefferson used to somehow mark his books.
Sorry for the length but last question, if I ever sold one of these should I disclose this and would it effect value. Example I have a 1st edition the stand. Very good condition. Looking on ebay this on would probably sell for 750 to 900. Would this cause it 50 bucks or whatever. I know, kinda hard to know since it's something u would never know was there. I work in a car factory and it's just like if there is a small dent on the inside of the deck lid that doesnt hurt performance and is then covered up with carpet pad, you never know it's there so it really doesn't matter.
