There has been ones that have sold for more, problem with the variety is they are only really rare in grades better than VF. When one does turn up in higher grades they have sold for good money although one less person wanting one. This is why the price of one like Ians is hard to accurately price and more just got to try them, although try them to high and collectors start to compare them with much better examples and ones in Fine there are plenty of for £25.
