I am so excited that I found this site and your awesome post. I just fell into a lot of Chinese coins, and I have at least 6 different Fat Man coins. I am very excited because I found, though your post, that I have a very rare variety. Photo 26. I posted a couple on ebay, under the same name that I am using here, and I really wish I saw this first! I was wondering, if you would mind if I put a link to this post in my next listing, because, OMG this is a wealth of knowledge!!!! So, now for my question. I have a variety that is not listed here. Right hand side of the obverse, approximately 4:00, there is a signature.... L. GIORGI Is this a fake? A special variety? I really need to know now! I hope you are still online, I would love to post some pictures of these and learn which ones they are! thank you soo much, again, for doing such a great posting!!
