Question

Suppose that you are a big fan of the Harry Potter books. You would love to own a copy of the very first printing of the first​ book, but unfortunately you​ can't find it for sale for less than​ $5,000. You are willing to pay at most​ $200 for a​ copy, but​ can't find one at that price until one day in a used bookstore you see a copy selling for​ $10, which you immediately buy. Are you being irrational if you keep the copy rather than sell it?

Answer 1

Answer:

I consider it wouldn't be irrational

Explanation:

Since you have now a collectible book that, in a few years more from now would cost even more.

Must of the antiques that didn't cost to much in certain time now can be in auction and people make a lot of money with them.  

When you have a collectible you need to find Collector Clubs or dealers, search over the internet and compare prices and then you can determinate when it is a good moment to sell.
