The month’s prospect is this rare SA Centenary FDC issued 09.08.1965. Postmarked Durham. Handpainted flagbearer (by – Chalmers/Riches?). Only seen once on Ebay, and to my luck, it was a “buy it now” auction with a bargain price. Cat. value £25 – £35. Rare UK FDCs will often be sold massively above catalogue prices. Estimated value: £80 – 100
