Dealers from as far afield as Auckland, Wellington and Palmerston North made the trip to the Whanganui Stamp and Coin Fair.
Whanganui Philatelic Society president Matt Bulman said people were waiting outside for the doors to open first thing yesterday morning.
"A lot of people come in with collections to sell, or just to get prices," Bulman said.
"Things can get passed down from family members, so we give them a ballpark figure of what they're worth.
"Then we can point them in the direction of the dealers who can help them.
