They're not getting any younger but stamp collectors are still around in decent numbers - and they still splash their cash around.
A stamp and coin auction running today and tomorrow at the West Plaza Hotel in Wakefield St in Wellington is expected to attract hundreds of bidders from both the global and domestic market.
The most prized lot, an excellent condition one penny full-faced Queen from New Zealand's first ever stamp issue, known as an SG1, is expected to fetch above its estimate of $10,000.
"'It's a hobby that appeals mostly to the generation of 50 to 60 plus," said auctioneer John Mowbray.
"It's a great hobby for people who are less active in their lives and have a bit of leisure time."
