I've made that mistake a few times also Bernie, so I know where you are coming from. Been there, done that, got the T-shirt many times, I've just wasted £10 on a standard 1863 penny, that looked a little odd in the photo. I spend a lot of time looking at coins on Ebay trying to find varieties, many of which are never listed even by experienced sellers - how many listings do you see for 1913 die pairings? I'm still trying to find a decent 1+B F175. 1909 F169 and 1908 F164a are still on the radar. I take the view, if I've done the leg work, and I'm prepared to get it wrong more often than not, then interesting items I do manage to buy at a low price are fair game.
