I wouldn't disagree in principle with anything people have posted on here about buying the best you can afford, and trying to get a minimum of EF grade. It's a perfectly sensible and practical way to go. However, there are a couple of caveats. Firstly, that's only really a workable policy for readily available coins and dates, unless that is, you have infinitely deep pockets, something most of us don't have. To give an example, if you are a collector of all coins Edward VII, you may well be able to obtain most coins in EF or better for reasonable money. However, if you are a completist, you will want a 1905 halfcrown (and florin and shilling) and you are not going to get these for reasonable money in EF. A halfcrown in Fine alone will likely set you back £500, whilst in UNC you could have to pay around £10k for the best. In this situation you have a choice. Either ignore the hole in your collection or accept that you have to lower your grading goals, at least for this one date and type. Most of us who are completists have this dilemma from time to time and we usually compromise our grading ideals. Only today, there's an example on another thread where davidrj has managed to complete a date run, but the final coin is in pretty low grade, but I bet he's happy to see the gap filled. http://www.predecimal.com/forum/topic/9947-still-a-completionist-at-heart/ The other point is that those who say that buying lower grade means an upgrade later with more cost are quite right for common coins. However, for less common ones, filling a gap and waiting for an upgrade may be the only way to have the satisfaction of achieving a collecting goal, but it may not cost you money either. For instance, I have a complete date run of halfpennies back to 1672. Of these just about the most difficult to find is the 1689. I bought a River Thames find in near fine condition for £400, some years ago and filled the gap. Eventually, I bought Nicholson's example which is in GF maybe NVF, as an upgrade. I have no expectation that I can find an EF example, and even if I could, that I could afford it, so I have to remain satisfied with the one I have. However, the Thames find subsequently sold for £450, so there was even an up side to the upgrade. I guess the point I'm making is that when it comes to rarities, the idea that upgrades will cost more than buying the best you can doesn't always apply. A final thought and that is that although you can see the ideals for collecting on here, don't run away with the idea that every coin collector only collects in absolutely top grade. It may seem so based on people's comments, but in reality most collectors compromise on some coins some of the time. If they didn't, you wouldn't see the volume of sales on ebay that you do, and dealers wouldn't even bother offering lower grade material, but they do, all the time. It doesn't make you a less serious collector, just because you don't always collect high grade. And finally, finally, for what it's worth, your half farthing seems a perfectly reasonable buy for £4 to me. No, it's not top grade, but it's not the worst either. Based on your pictures, wear is very even all round and the colour looks nice, and I reckon you'd easily get your money back on ebay if you wished.
