Is your Harry Potter Book worth £20k - Bitter Wallet
Now Ireth... How much do you LOVE that book?
I've heard that too; also that it's only those with the numbers "10 9 8 7 6 5 4 3 2 1" on the page with all the copyright info which are that valuable. The numbers in my copy only go down to 4, and another friend has a typo'd copy with numbers down to 7. Makes me wonder if those are still valuable, only less so.
