This Harry Potter book with tea stains and folded corner auctioned for Rs 38 lakh - What makes it special?

The book is one of just 500 hardback copies produced during the first print run in 1997, which has made it a rare gem among collectors. According to Hansons Auctioneers, the book was initially valued between £30,000 and £50,000, based on its rarity and condition.
The McCulloch family, however, did not recognize the book’s value until the 2020 lockdown when they read about the rising prices of first editions. "Once we got it verified, it was a bit of a pinch-yourself moment," said Adam McCulloch, who hails from Tansley, Derbyshire. "In some ways, I think having that bit of a story around it, some tea stains there and a folded-over corner here where someone’s enjoyed reading it – I think that adds to the magic."
The book had been stored in a cupboard under the stairs of the family’s former home in Chesterfield, untouched for years. It wasn’t until the family became aware of the book’s potential that they decided to have it authenticated. Adam believes that the imperfections, such as the stains and worn edges, only add to its charm and historical value.
