Peter Simpfendorfer’s ability to answer the most left-field trivia questions comes from more than 50 years of stamp collecting.
Mr Simpfendorfer said a lot can be learned about politics, flora and fauna, history and world flags through an extensive stamp collection.
“The appeal to me is the knowledge I can get from collecting stamps,” he said.
Exhibitors from Melbourne, Sydney, Canberra and Orange showed their wares to more than 400 visitors to the Wagga Stamp and Coin Fair at the weekend.
Big sales, such a gallon drum half-full of pennies, a bag of badges and a stamp collection that sold for four figures, were made.
“If we didn’t have the fair twice a year that allowed them to dispose of this material, they’d have to sell through auction,” Mr Simpfendorfer said.
“People have probably been hoarding these items as an investment.
“People don’t come out of curiosity, they come to buy or sell.”
The next Wagga Stamp and Coin Fair will be held at Sturt Public School on May 21 and 22 next year.
