I have been sorting out some stamps to sell online from a load we found in the loft when we moved here, and I am mystified by some (I am not a stamp collector or fan). They have UK prices on, are quite large, no frills around the edge like most stamps, and have the word "staffa" on them. There are postmarks on them that say Staffa, Scotland.
Are they stamps, or what are they> what should I list them under? what sort of price should I list them for? Are they Royal Mail issues or from somewhere else?
Thanks tons for any advice.
(hope its OK to post a picture, sorry its not great just grabbed a quick snap)
