Congrats on showing the initiative to search some prior posts... Yup, this is another specimen of that fake - that "die crack" makes this particular one easy to confirm. As I mentioned back then, this piece is similar in terms of characteristics to some of the (invariably bogus) pieces that appear in Postal Commemorative Society folders (though I'm not certain that I've actually seen this particular one in that packaging). Little doubt that this one and those others are fairly modern numismatic fakes...
