My elderly father has an extensive collection of cast iron that he looking to sell. He specialized in Wapak but also had a lot of other brands in his collection. Looking for suggestions how to best sell his collection. Leaning towards auction that would include online bidding. Any suggestions on auctioneer or auction house that specializes in cast iron. Also looking for best way to notify collectors of the sale. Would obviously use this site but would appreciate any other sites that would help notify collectors. Thanks in advance
