The disappearance of a retired Napier businessman's collection of stamps dating back 163 years is heightening fears the priceless albums will be abandoned and destroyed.
He hopes a public appeal will lead to the collection being recovered undamaged.
The collection, which includes covers and envelopes addressed to such people as missionary and Treaty of Waitangi signing witness William Colenso and fellow late 1850s Napier MP Douglas MacLean, was stolen in the burglary of a Hospital Hill home on May 3, despite being in a safe.
Stamp thefts are rare and the collector says the burglars would not have known what they were taking when they removed the locked safe, which was found a few days later cut open on a Tukituki River bank near Haumoana.
Missing were the two plum-brown covered albums, each approximately 30cm x 25cm, and two black-and-blue stock books, together containing about 300 stamps.
