Property not claimed after three months is sold at auction, with all proceeds going towards running costs of the lost property office.
One in two items of value are successfully returned to owners while the return rate for other items is one in three for bags, one in four for mobile phones and one in five for books.
The overall return rate for all items is about one in 12. Transport for London made clear that although some unclaimed common items were on display in the windows at the Baker Street office, there was no public display of unusual objects.
