SOUTHAMPTON, Pa. – Before offering someone a penny for their thoughts, it might be wise to examine the penny first. Even a humble one-center can be worth a fortune if it’s the right type, like the 1943-D Lincoln penny that sold for $1.7 million in 2018. Coin collecting is one of the world’s most popular hobbies and a favorite category with Stephenson’s Auction’s nationwide bidding audience. The next chance to go coin-hunting at Stephenson’s, whether for fun or investment, comes on Sunday afternoon, October 23rd, at the company’s sale of an estate collection from Bucks County (suburban Philadelphia).
