Enter one admittedly biased opinion. The Ultimate Guide to Conder Tokens is a great reference for the series. I finished the first edition a around this time last year.Speaking for myself, I find it particularly useful to have a digital reference on my computer desktop because essentially all of my collecting of this series is done somehow through online sales, be it at auctions, Cheapside tokens, Bill McKivor, Gary Groll, Dave Stuart, etc. That was one of main reasons that I created it. I like having hardcopy references but the book is huge and the Conder series is so massive that I often wished I had something that was digitized so that I could execute searches, etc. Plus, the digital DH has a more streamlined formatting and includes integrated rarity ratings that you'll have to search through footnotes for in the hardcopy. That's just my opinion though...and like I said, a biased one. Though I have received feedback from a good number of collectors that like it for very much the same reasons. Also, the second edition is currently being hashed out and will contain individual pricing info for many, many tokens. Will keep you all posted on that.
