Thanks for your replies guys. I think it’s the fact that it is very random that appeals. It could be a way of escaping (or supplementing) the single denomination date run scenario for me. They are obviously going to be unique coins, with potential too create a unique collection and within my price range especially if I only acquire one or two a year and since there isn’t an abundance of examples out there, there is less chance of being seduced into buying for the sake of it…..I must however only choose ones I really like!!! Does anyone know of any literature available on this subject? Oh and yes please if anyone happens across anything that might be of interest please do let me know! Ever grateful
