Philip II. 247-249 AD. AR Antoninianus (23mm, 4.47 g). Antioch mint. 1st issue. IMP M IVL PHILIPPVS AVG, radiate, draped, and cuirassed bust right, seen from behind / P M TR P VI COS P P, Philip standing left, holding transverse scepter and sacrificing with patera over altar to left. RIC IV 236;McAlee p. 327, fig. 30A (this coin illustrated). As someone who generally prefers online references to books (I know, I know, not the most popular thing to say here), I'll admit that I had never quite understood what the big deal was about owning a "plate" coin, but I completely get it now. It really was a pretty cool experience to open up an actual book and see a picture of my coin on the pages...much more fun than I expected it to be. Here's a photo of both sides of my coin next to the illustration in the book: I think that McAlee's book is really an excellent reference. Though I usually just rely on online sources, I now have enough coins from Antioch and the Eastern mints that I figured it was time to get a more specialized reference. I was a little hesitant to spend the money on the book, but I'm SO happy that I did. Basically, for the price I would have paid to buy one more tetradrachm, I ended up getting a book that helped me understand so much more about the coins that I already have, and the ones I'll be adding in the future. The book is well-organized, easy to follow, has lots of great photos, and just has a ton of interesting information and detail. It focuses on the provincial coinage of Antioch (mine is one of the few Imperial coins illustrated in the book), but I think the author really did a great job of highlighting the coinage of each emperor, and the changes over time. I really wish I 'd bought this book much earlier, would highly recommend it to anyone! Please post your "plate" coins (whether illustrated in a book or an online source), any coins from the McAlee collection, Philip II coins, or anything else relevant!
