"I've managed to whittle my own collection down a little bit in terms of a specific focus, because that can be a problem with collections.

"As a history-trained geography teacher, I look at postmarks. There have been close to 7000 post offices opened in New Zealand throughout our history.
"If you can find a mark from a very rare post office - one that was only open for three weeks during the war, for example - that can make a 10 cent stamp worth $500."

Whanganui coin dealer Craig Morris said he had been in the business since 1979.
"It's surprising how many people collect," Morris said.
"Years ago you'd want to collect one of each date, pennies and things like that, but now people are getting more into presentation sets, silver, gold, and looking towards more of an investment as well as a pastime.
"They all collect for different reasons, it's anything and everything, and it's great that it's still really popular."
