Hey MoParlover. Just check if your AMC Issue One is from the original print run or a Collectors Reprint. If it doesn't have the words 'Collectors Reprint' next to the barcode on the cover, then you have one of the originals, which are quite rare because the print run was less than 10,000 copies (check page three and you might be surprised who the founding editor was). I've heard of pristine copies changing hands online for three figures, so you could do an eBay auction and see how you go.
